If he is walking in darkness, he isn't a Christian.
"Brother" has more than just one connotation.
That's your opinion based on your indoctrination from your denomination.
Again, I asked you where in the passage does John shift from addressing Brothers in Christ to addressing the unsaved.
You keep stating your opinion but you refuse to point out where in the actual verse that John is no longer addressing brothers in Christ.
But he who hates his brother is in darkness and walks in darkness,...
"his brother" refers to two brothers in Christ.
The one brother for whatever reason begins to hate his brother.
John is warning the brethren that they must guard themselves against allowing an offense to anger them to the point of hating their brother.
Again here is the context -
1 My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. 2 And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
The Test of Knowing Him
3 Now by this we know that we know Him, if we keep His commandments. 4 He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him. 5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him. 6 He who says he abides in Him ought himself also to walk just as He walked.
7 Brethren, I write no new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word which you heard from the beginning. 8 Again, a new commandment I write to you, which thing is true in Him and in you, because the darkness is passing away, and the true light is already shining.
9 He who says he is in the light, and hates his brother, is in darkness until now. 10 He who loves his brother abides in the light, and there is no cause for stumbling in him. 11 But he who hates his brother is in darkness and walks in darkness, and does not know where he is going, because the darkness has blinded his eyes. 1 John 2:1-11
- He who loves his brother abides in the light, and there is no cause for stumbling in him. V.10
- But he who hates his brother is in darkness... V.11
Verse 10 refers to two brothers in Christ.
Verse 11 refers to two brothers in Christ.
The brother who hates is in danger of no longer having eternal life remaining in him, if he doesn't repent.
That's John's point to write this warning, to exhort us to forgive and to continue loving.
13 Do not marvel, my brethren, if the world hates you. 14 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. 15 Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him. 1 John 3:13-15
John makes a clear distinction between the world and the brethren he is addressing as he plainly states "my brethren".
- Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
Again, the warning is clear, brothers in Christ who begin to hate their brother, for whatever reason, will no longer have eternal life abiding in them if they don't repent and confess their sin so as to be forgiven and cleansed of that unrighteousness.
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make Him a liar, and His word is not in us. 1 John 1:8-10
- If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
- If we say that we have not sinned, we make Him a liar, and His word is not in us.
Brothers in Christ must confess their sin in order to be forgiven and cleansed of all unrighteousness.
My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. And He Himself is the propitiation for our sins, and not for ours only but also for the whole world. 1 John 2:1-2
- He Himself is the propitiation for our sins, and not for ours only but also for the whole world.
Our sins = brothers in Christ
The world = Unsaved
