Hello. You have provided the text to which this question refers, but we can say that Rome is an unlikely choice as the location of an important Christian church because of its polytheistic past.
Explanation:
Today Rome is the center of the Christian religion, being the most influential and important city for that religion, even though it was not formed based on any Christian concept and has spent centuries as a region of Poleithist religion, where there was a mixture of Greek gods and growths and oriental. This polytheistic past, outside of the Cyrtic/Jewish roots, made Rome a very unlikely place to be the center of Christianity.
If you accidentally place a 20 gauge shell in a 12 gauge shotgun it will most likely cram the barrel. This can very seriously injure the person using it and the gun immensely.
