This might help a little.
Remember Matt 16:15-18
When Simon Barjona answers positively to Jesus Christ, as to who He was, our Lord responds by noting, “Blessed art thou, Simon Barjona, for flesh and blood hath not revealed it unto thee, but by my Father which is in heaven.”
It wasn’t the soul or body which had revealed the identity of Jesus as the Christ, the Son of God, but rather God the Father. Notably, it is upon THIS rock that Christ builds His Church. The rock which is established by God the Father.
“This might help a little.”
None of that changes the fact that is was Jesus Who called Saul on the road to Damascus.
