Uh, Gamecock, this is not something Catholics are taught, and yet the protestants take this as proof that protestants know more than Catholics ... this is a straw argument used by the protestants, and it is false.
Once again the councils of the Church got it wrong. There is no Nestorian heresy. Glad the modern day reformers could clear that up.
Indeed they are taught this...maybe you have not graduated far enough yet to the next level of teaching. Perhaps better said is catholics are in a grave state of denial of what their church really teaches.
Idolatry, no matter how a catholic might frame it...is just that.... and as God has said..those who practice this become like the idols they worship...blind and can't hear. So it is perfectly understandable why catholics cannot see the truth. Thus it is an easy thing for them to justify to themselves what they do....So don't those who live together before marriage...or have sex before marriage and then wonder why they run into magnifold problems thereafter. They are unwilling to give up the relationship...and it is most difficult to turn it around and do it right. So too catholics cannnot let go of the relationship with their church...and the church will not let go easily either. It has it's members bound.
Until the idolatry is put away, which they have brought into the church, along with the goddess worship of Mary they will not see the truth. Rather a fearful judgment of God to come...if not already happening and I think it has in recent years been revealed as so.
