Through out history they (we) lacking in THE knowledge of the Christ nature & character have been seduced & have seduced others into countless murders (hate), over who is the anti-Truth, also called the antichrist, anti-love & the like, such negative judgement is based on a lack of love's knowledge.
The antichrist is any of us who reject The Spirit Of Eternal Truth's way, in favor of any other teaching, even Peter was where Jesus rebuked him, calling him Satan for the rejection of God's will. Other words you & I are 1 with the antichrist any where we reject The Spirit Of Truth's leading that Jesus is quoted saying he would send to lead any who will follow into all/All's Truth, Genesis 1:26
