OK, this has been bothering my brother for quite some time, and I couldn’t help him.
We all know that Jesus said to baptize “in the name of the Father, and of the Son, and of the Holy Spirit”. Matt 28:19.
But several times in Acts, the Apostles Baptize in “the name of Jesus Christ” only, neglecting “the Father” and “the Holy Spirit”.
So my brother’s friend, a Unitarian Pentecost, claims that Jesus is God, in one person - no Trinity. If you point out that Jesus was sent by “Whom?”, you’re just wasting your time. He just keeps questioning, why did our first Pope get this major point wrong. Isn’t this a False Teaching, he asks.
Can you help two brothers in need?
