I was astonished to read your e-mails.
Acts 2:33 is indeed the "first sermon in the history of Christianity" (as
Thomas Kopecek wrote).
Now I will quote from some words of Peter a little later:
Acts 5:3 - 4: Peter said: "Ananias, why has Satan filled your heart to lie
to the Holy Spirit ... You have not lied to men but to God." Acts 5:9 But
Peter said to her (that is, Sapphira), "How is it that you have agreed
together to tempt the Spirit of the Lord? ..."
This verses proof, that Peter had a clear awareness of a Holy Spirit being
a) a person (How could Ananias have lied to a thing or force ?)
b) divine (5:4 !)
As to Luke 2:25, I encourage again to look at the context:
Luke 2:26 "And it had been revealed to him by the Holy Spirit that he should
not see death before he had seen the Lord's Christ." Its difficult for me
to imagine somebody (something ?) that is able to reveal something while
being no person but a thing (force, abillity ?).
Look also at Acts 8:29; 13:2.4; 16:6-7 etc.
