Sorry, I don’t get your reference.
Jesus said (Luke 24:48-49) “You are witnesses of these things. And behold I am sending forth the promise of My Father upon you but you are to STAY IN THE CITY UNTIL YOU ARE CLOTHED WITH POWER FROM ON HIGH.” (caps mine)
The “Power from on high” was the Holy Spirit, which came on the Church on Pentecost.
That “Power” changed Peter from an illiterate fisherman to one of the most articulate speakers in history...
that “Power” began the Church.
Sometimes my mind moves faster than my fingers and I don't type in everything I should. What I was getting at was at what point did the Christian Church emerge.
Your point about the Holy Spirit descending on believers is right, but at that point these believers still thought of themselves as Jews and maintained Temple worship.
that “Power” began the Church.
I would say you're right, but at that time it was not Christian. It was almost exclusively Jewish.
