My dearly-loved friends, it is no new command that I am now giving you, but an old command which you have had from the very beginning. By the old command I mean the teaching which you have already received.

They have gone forth from our midst, but they did not really belong to us; for had they belonged to us, they would have remained with us. But they left us that it might be manifest that professed believers do not all belong to us.

He who is destitute of love has never had any knowledge of God; because God is love.
