Be sure to hold their feet to the fire and know just who they claim the Holy Trinity is. If Jesus does not have the pre-eminence in all things, and Mary is the first-born of all creatures as one of the popes asserted, speaking infallibly to the whole church, then they are not of the church of Jesus Christ. You would be unequally yoked with such, and have nothing in common.
As the members of this sect learn what their church believes they will either embrace it, or reject it. My unity is with those that embrace the gospel, regardless of the sect they are in, and it is those fellow brothers and sisters in CHRIST I look forward to being yoked with.
Which Pope claimed that Mary is the firstborn?
I’m not sure I’ve run into that one before.
