Zero proof that Stephen was seeing Jesus when he prayed to Him.
The vision took place in the city. The prayer took place afterwards when Stephen was dragged out of the city (Acts 7:58).
You're right.
Still, as I say, it is perfectly fine if you ever want to talk to Jesus. He is an intercessor.
Jesus never taught to pray only to the Father.
That's true. Then, are Catholics OK in praying to the saints and Virgin Mary?
Jesus never taught to pray
only to the Father right?
And what about being baptized for your dead relatives or friends, as some contemporary of Paul did?
Jesus never taught that you should be baptized
only for yourself.
What about replacing wine by water in the celebration of the Last Supper as the Mormons do?
Jesus never taught that their disciples should use
only wine.
Paul also thanked Jesus (1 Timothy 1:12).
Sure, and that is great. I also thank Jesus.
But when Paul thanked Jesus, Paul didn't call Him God.
in contrast, when Paul thanked his Father, Paul called him God.
No. The Father and Son are the same being, but not the same Person.
One single being could not be sitting at the right of Himself and he could not be
called and
not called God at the same time.
So we must admit that Stephan saw two persons, one sitting next to the other.
He called "God" to only one of them: the one who was not the Son of Man.
