In your religion obviously, but not in biblical Christianity...
The argument, however, is circular. The assumption implicit in citing them is that the true church somehow ceased about a generation after the death of John. And this assumption requires that the promised gift of the spirit was kind of a dud. In the protestant view it took the Holy Spirit about 1500 years to get his act together enough to make a successful stand against those awful, stupid, and superstitious successors of the Apostles.
Not accurate at all...We do know that the 'true church' didn't die off in spite of your religion's attempt to snuff it out and burn it's scriptures...
There was however always a remnant to pass along and preserve what God had revealed...
So when Jesus promised the 12 that they would be led into all truth, he left out the part about in 1450 years give or take.
The Holy Spirit was not promised to just the 12...All Christians are indwelt with that same Spirit that leads to all truth and raised Jesus from the dead...That Spirit of Truth...
The fact that so many reject the written truth of God is evidence that the 'flesh', the 'old man', still has plenty of power and is resistant...
In any religion, the facts of English etymology are still facts. The English word 'priest' is derived from the Greek word presbyteros, no matter where or whom you worship.
I'm not going to read the rest of a post which starts with trying to make a philological observation into a sectarian slander.
