It's "offensive" because a "biblical Christian" A.K.A. a protestant adopts the view that Christ is exclusive to them. It's not Christ that is offended, but your "personal relationship" that is threatened. And so, like the jealous spouse the protestant reacts in kind. Christ honors His Mother. Protestants should do likewise.
As an aside, I will never concede that I am not a biblical Christian. The bible is not the exclusive province of the protestant even though on the surface it's an effective polemic for it ostensibly puts the Catholic on the defensive of having to argue that they are biblical Christians.
It's the theological equivalent of, "Have you stopped beating your wife?" It's not unexpected, however. In the grand scheme of things, however, Catholics are playing chess while protestants are playing checkers or pleasuring themselves mentally with their supposed wit.
the Mary of Catholicism is not the Mary of the Bible, but a dangerous distortion that has led multitudes into idolatry and a false salvation hope.
False dichotomy which stems from the notion that sola scriptura is the sole rule of faith. If it isn't explict within Scripture then it is not so. The bifurcation of Sacred Scripture and Sacred Tradition. A rather recent and novel invention. Protestants leave out half the story. Convenient for establishing new "doctrines."
Yet here we are - experiencing the Spirit, having never uttered a prayer to any saint... having never experienced the 'true eucharist', having never confessed to a 'priest', having *none* of your 'sacred tradition' (me more than most)... Makes one wonder at the efficacy of all that stuff, when a personal relationship with the Father through Messiah seems to do the trick just fine.
Matthew 12:48 But he answered and said unto him that told him, Who is my mother? and who are my brethren? 49 And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren!
I've NEVER seen any data to support this slur.
Do YOU have any to direct a searcher to?
