First John Chapters (English Bible : Catholic Public Domain Version – CPDV)
1 Most beloved, do not be willing to believe every spirit, but test the spirits to see if they are of God. For many false prophets have gone out into the world.
2 The Spirit of God may be known in this way. Every spirit who confesses that Jesus Christ has arrived in the flesh is of God;
3 and every spirit who contradicts Jesus is not of God. And this one is the Antichrist, the one that you have heard is coming, and even now he is in the world.
4 Little sons, you are of God, and so you have overcome him. For he who is in you is greater than he who is in the world.
5 They are of the world. Therefore, they speak about the world, and the world listens to them.
6 We are of God. Whoever knows God, listens to us. Whoever is not of God, does not listen to us. In this way, we know the Spirit of truth from the spirit of error.
7 Most beloved, let us love one another. For love is of God. And everyone who loves is born of God and knows God.
8 Whoever does not love, does not know God. For God is love.
9 The love of God was made apparent to us in this way: that God sent his only-begotten Son into the world, so that we might live through him.
10 In this is love: not as if we had loved God, but that he first loved us, and so he sent his Son as a propitiation for our sins.
11 Most beloved, if God has so loved us, we also ought to love one another.
12 No one has ever seen God. But if we love one another, God abides in us, and his love is perfected in us.
13 In this way, we know that we abide in him, and he in us: because he has given to us from his Spirit.
14 And we have seen, and we testify, that the Father has sent his Son to be the Savior of the world.
15 Whoever has confessed that Jesus is the Son of God, God abides in him, and he in God.
16 And we have known and believed the love that God has for us. God is love. And he who abides in love, abides in God, and God in him.
17 In this way, the love of God is perfected with us, so that we may have confidence on the day of judgment. For as he is, so also are we, in this world.
18 Fear is not in love. Instead, perfect love casts out fear, for fear pertains to punishment. And whoever fears is not perfected in love.
19 Therefore, let us love God, for God first loved us.
20 If anyone says that he loves God, but hates his brother, then he is a liar. For he who does not love his brother, whom he does see, in what way can he love God, whom he does not see?
21 And this is the commandment that we have from God, that he who loves God must also love his brother.
