Sam: It is well known certain things were put in to many seforim at the behest of the censors. This has long been accepted in the Torah community. One of the more famous instances is in the Aruch Hashulchan where he praised the benevolent Czar of Russia as a great friend and protector of the Jews and then rules that mesira doesn’t apply when it comes to such a friend of the Jews as the Czar.
And with issue at hand, as shituf directly relates to Christianity the seforim could not freely describe Christianity as idol worship and hope the Church censors would allow its publication.
