Children, it is the last hour, and just as you heard that the antichrist is coming, so now many antichrists ¹  have appeared. We know from this that it is the last hour.

For ¹  many deceivers have gone out into the world, people who do not confess Jesus as ²  Christ ³  coming in the flesh. ⁴  This person is the deceiver and the antichrist! ⁵ 

Who is the liar but the person who denies that Jesus is the Christ ¹ ? This one is the antichrist: the person who denies the Father and the Son.
