Acts 3:14-19 Douay-Rheims 1899 American Edition (DRA)
14 But you denied the Holy One and the Just, and desired a murderer to be granted unto you.
15 But the author of life you killed, whom God hath raised from the dead, of which we are witnesses.
16 And in the faith of his name, this man, whom you have seen and known, hath his name strengthened; and the faith which is by him, hath given this perfect soundness in the sight of you all.
17 And now, brethren, I know that you did it through ignorance, as did also your rulers.
18 But those things which God before had shewed by the mouth of all the prophets, that his Christ should suffer, he hath so fulfilled.
19 Be penitent, therefore, and be converted, that your sins may be blotted out.
Douay Rheims/ American version 1899
I don't see the issue here. Paul is trying to convert the jews. . Converted jews are Christians . The Church, initially comprised of converted jews is the true Israel. Those jews not converted bear the curse they placed upon themselves. The religious jews of today KNOW who Christ is, but they reject Christ and therefore reject God the Father as the Holy Trinity is indivisible. They reject Moses and the Law because they did not recognize or rejected God in their midst. They worship another "god" or gods and want to bring about the destruction of non-jews through through supremacy of the "jewish people" who collectively will rule the nations as "messiah" and will usher in a satanic anti-christ as they have already brought with them the anti-christ spirit of control. The church says the jews ( but maybe not the luciferian type) will be converted in the last days as a tenant of Christ's return. The modern jews are a demonically controlled race who have little to do with the quasi-innocence of the jews Paul was speaking to and probably converted.
Revelation 3:9 " Beware those who say they are jews but are not'.
Well what are they then? hmmmmm
