The Heidelberg Catechism Part II: Deliverance The Church & Forgiveness, Part 1 Lord’s Day 21
Question 54: What do you believe concerning “the holy catholic church”?
Answer 54: I believe that the Son of God through his Spirit and Word  out of the entire human race,  from the beginning of the world to its end,  gathers, protects, and preserves for himself a community chosen for eternal life  and united in true faith.  And of this community I am  and always will be  a living member.
 John 10:14-16 NKJV I am the good shepherd; and I know My sheep, and am known by My own. (15) As the Father knows Me, even so I know the Father; and I lay down My life for the sheep. (16) And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd.
Acts 20:28 NKJV Therefore take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood.
Romans 10:14-17 NKJV How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? (15) And how shall they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!" (16) But they have not all obeyed the gospel. For Isaiah says, "Lord, who has believed our report?" (17) So then faith comes by hearing, and hearing by the word of God.
Colossians 1:18 NKJV And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence.
 Genesis 26:3-4 NKJV Dwell in this land, and I will be with you and bless you; for to you and your descendants I give all these lands, and I will perform the oath which I swore to Abraham your father. (4) And I will make your descendants multiply as the stars of heaven; I will give to your descendants all these lands; and in your seed all the nations of the earth shall be blessed;
Revelation 5:9 NKJV And they sang a new song, saying: "You are worthy to take the scroll, And to open its seals; For You were slain, And have redeemed us to God by Your blood Out of every tribe and tongue and people and nation,
 Isaiah 59:21 NKJV "As for Me," says the LORD, "this is My covenant with them: My Spirit who is upon you, and My words which I have put in your mouth, shall not depart from your mouth, nor from the mouth of your descendants, nor from the mouth of your descendants' descendants," says the LORD, "from this time and forevermore."
1 Corinthians 11:26 NKJV For as often as you eat this bread and drink this cup, you proclaim the Lord's death till He comes.
 Matthew 16:18 NKJV And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it.
John 10:28-30 NKJV And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. (29) My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand. (30) I and My Father are one."
Romans 8:28-30 NKJV And we know that all things work together for good to those who love God, to those who are the called according to His purpose. (29) For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. (30) Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
Ephesians 1:3-14 NKJV Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, (4) just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, (5) having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, (6) to the praise of the glory of His grace, by which He made us accepted in the Beloved. (7) In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace (8) which He made to abound toward us in all wisdom and prudence, (9) having made known to us the mystery of His will, according to His good pleasure which He purposed in Himself, (10) that in the dispensation of the fullness of the times He might gather together in one all things in Christ, both which are in heaven and which are on earth—in Him. (11) In Him also we have obtained an inheritance, being predestined according to the purpose of Him who works all things according to the counsel of His will, (12) that we who first trusted in Christ should be to the praise of His glory. (13) In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise, (14) who is the guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.
 Acts 2:42-47 NKJV And they continued steadfastly in the apostles' doctrine and fellowship, in the breaking of bread, and in prayers. (43) Then fear came upon every soul, and many wonders and signs were done through the apostles. (44) Now all who believed were together, and had all things in common, (45) and sold their possessions and goods, and divided them among all, as anyone had need. (46) So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, (47) praising God and having favor with all the people. And the Lord added to the church daily those who were being saved.
Ephesians 4:1-6 NKJV I, therefore, the prisoner of the Lord, beseech you to walk worthy of the calling with which you were called, (2) with all lowliness and gentleness, with longsuffering, bearing with one another in love, (3) endeavoring to keep the unity of the Spirit in the bond of peace. (4) There is one body and one Spirit, just as you were called in one hope of your calling; (5) one Lord, one faith, one baptism; (6) one God and Father of all, who is above all, and through all, and in you all.
 1 John 3:14 NKJV We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death.
1 John 3:19-21 NKJV And by this we know that we are of the truth, and shall assure our hearts before Him. (20) For if our heart condemns us, God is greater than our heart, and knows all things. (21) Beloved, if our heart does not condemn us, we have confidence toward God.
 John 10:27-28 NKJV My sheep hear My voice, and I know them, and they follow Me. (28) And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
1 Corinthians 1:4-9 NKJV I thank my God always concerning you for the grace of God which was given to you by Christ Jesus, (5) that you were enriched in everything by Him in all utterance and all knowledge, (6) even as the testimony of Christ was confirmed in you, (7) so that you come short in no gift, eagerly waiting for the revelation of our Lord Jesus Christ, (8) who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ. (9) God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord.
1 Peter 1:3-5 NKJV Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant mercy has begotten us again to a living hope through the resurrection of Jesus Christ from the dead, (4) to an inheritance incorruptible and undefiled and that does not fade away, reserved in heaven for you, (5) who are kept by the power of God through faith for salvation ready to be revealed in the last time.
Q 55: What do you understand by “the communion of saints”?
A 55: First, that believers one and all, as members of this community, share in Christ and in all his treasures and gifts.  Second, that each member should consider it a duty to use these gifts readily and joyfully for the service and enrichment of the other members. 
 Romans 8:32 NKJV He who did not spare His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?
1 Corinthians 6:17 NKJV But he who is joined to the Lord is one spirit with Him.
1 Corinthians 12:4-7 NKJV There are diversities of gifts, but the same Spirit. (5) There are differences of ministries, but the same Lord. (6) And there are diversities of activities, but it is the same God who works all in all. (7) But the manifestation of the Spirit is given to each one for the profit of all:
1 Corinthians 12:12-13 NKJV For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. (13) For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit.
1 John 1:3 NKJV that which we have seen and heard we declare to you, that you also may have fellowship with us; and truly our fellowship is with the Father and with His Son Jesus Christ.
 Romans 12:4-8 NKJV For as we have many members in one body, but all the members do not have the same function, (5) so we, being many, are one body in Christ, and individually members of one another. (6) Having then gifts differing according to the grace that is given to us, let us use them: if prophecy, let us prophesy in proportion to our faith; (7) or ministry, let us use it in our ministering; he who teaches, in teaching; (8) he who exhorts, in exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness.
1 Corinthians 12:20-27 NKJV But now indeed there are many members, yet one body. (21) And the eye cannot say to the hand, "I have no need of you"; nor again the head to the feet, "I have no need of you." (22) No, much rather, those members of the body which seem to be weaker are necessary. (23) And those members of the body which we think to be less honorable, on these we bestow greater honor; and our unpresentable parts have greater modesty, (24) but our presentable parts have no need. But God composed the body, having given greater honor to that part which lacks it, (25) that there should be no schism in the body, but that the members should have the same care for one another. (26) And if one member suffers, all the members suffer with it; or if one member is honored, all the members rejoice with it. (27) Now you are the body of Christ, and members individually.
1 Corinthians 13:1-7 NKJV Though I speak with the tongues of men and of angels, but have not love, I have become sounding brass or a clanging cymbal. (2) And though I have the gift of prophecy, and understand all mysteries and all knowledge, and though I have all faith, so that I could remove mountains, but have not love, I am nothing. (3) And though I bestow all my goods to feed the poor, and though I give my body to be burned, but have not love, it profits me nothing. (4) Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; (5) does not behave rudely, does not seek its own, is not provoked, thinks no evil; (6) does not rejoice in iniquity, but rejoices in the truth; (7) bears all things, believes all things, hopes all things, endures all things.
Philippians 2:4-8 NKJV Let each of you look out not only for his own interests, but also for the interests of others. (5) Let this mind be in you which was also in Christ Jesus, (6) who, being in the form of God, did not consider it robbery to be equal with God, (7) but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. (8) And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross.
Q 56: What do you believe concerning “the forgiveness of sins”?
A 56: I believe that God, because of Christ’s satisfaction, will no longer remember any of my sins  or my sinful nature which I need to struggle against all my life.  Rather, by grace God grants me the righteousness of Christ to free me forever from judgment. 
 Psalms 103:3-4 NKJV Who forgives all your iniquities, Who heals all your diseases, (4) Who redeems your life from destruction, Who crowns you with lovingkindness and tender mercies,
Psalms 103:10-12 NKJV He has not dealt with us according to our sins, Nor punished us according to our iniquities. (11) For as the heavens are high above the earth, So great is His mercy toward those who fear Him; (12) As far as the east is from the west, So far has He removed our transgressions from us.
Micah 7:18-19 NKJV Who is a God like You, Pardoning iniquity And passing over the transgression of the remnant of His heritage? He does not retain His anger forever, Because He delights in mercy. (19) He will again have compassion on us, And will subdue our iniquities. You will cast all our sins Into the depths of the sea.
2 Corinthians 5:18-21 NKJV Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, (19) that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. (20) Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ's behalf, be reconciled to God. (21) For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.
1 John 1:7 NKJV But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.
1 John 2:2 NKJV And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
 Romans 7:21-25 NKJV I find then a law, that evil is present with me, the one who wills to do good. (22) For I delight in the law of God according to the inward man. (23) But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. (24) O wretched man that I am! Who will deliver me from this body of death? (25) I thank God—through Jesus Christ our Lord! So then, with the mind I myself serve the law of God, but with the flesh the law of sin.
 John 3:17-18 NKJV For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. (18) "He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
Romans 8:1-2 NKJV There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. (2) For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death.
