What was unscriptural about the original post?
This is part 2 of a 12 part article, posted as one article,, but being presented in 12 installments here on FR. It is just more Spam from the cult. In it's entirety, it represents Roman Catholic ideas which are in contrast to Scripture, and entirely based on their extra-Biblical "traditions". Though parts of it such as this one seem innocuous, in sum they are like rat poison... 90% food, 10% poison that kills every time.
Like the Mormon cult, they claim Jesus as part of their credo, but they elevate Mary to co-Redemptrix status. They also teach that Muslims worship the same god as Christians and though this article leads one to believe otherwise, they allow for the fact that all who worship that god will be together in the end. I agree with that part.
Lumen Gentium (1964):
This documents affirmed that the plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Moslems: these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankinds judge on the last day.
