When you think about modern Christian heresies, the two biggest that come to mind are Jehovah's Witnesses with about 8 million active members,

and Mormonism with about 17 million adherents. But there's another huge heresy among self-professed Christians you rarely hear about,

even though it's just as detrimental to the soul, and that is oneness theology, often found among oneness Pentecostals.

There are about 17 million oneness Pentecostals worldwide, making them on par with Mormonism.

just is Jesus. According to them, the terms Father, Son, and Holy Spirit do not refer to three

distinct persons, but to three manifestations of God, or three roles that God plays in our salvation.

That's why Onus Mentecostals have an invalid baptism that only uses Jesus' name.

I now baptize you in the name of Jesus Christ for the remission of all your sins.

as the Father in Creation, as the Son in Redemption,

and as the Holy Spirit in renewing believers' hearts. Here's David Bernard, a leading defender
