It just may be, Dear Kosta, that Holy Spirit within us is rising up and screaming an alarm that is worthy and fitting--particularly to a structure, pattern, degree of error--that for some RC's etc. is spiritually more than hazardous.
This business such as:
faulty Mariology = faulty Christology; functionally, logically yields Mary = Jesus.
Just screams of inappropriate emphases on Mary. At best, Mary is a distraction. At worst and far too often for far too many unthoughtful folks, Mary becomes an idol replacing focus, adoration, worship that GOD ALONE warrants, deserves, allows to be the focus of such attitudes, thoughts, practices.
We are talking, Dear Kosta, about a pattern of thought and behavior, which, under the Old Testament meant immediate stoning to death. For many of us Proties--it's not a light OPTIONAL thing--AT ALL.
And, we don't take protestatinos and rationalizations very seriously because we all have been very good at rationalizing and protesting our own petty and not so pety idoltries in our own religious and even our own spiritual walks. We have all been, at various times . . . none so blind as those who WILL NOT see. So, we assume that RC folks are AT LEAST AS HUMAN AS WE ARE--vis a vis denial, willful and other blindness; the comforts of substitutes for God etc.
Why not go after real "spiritually hazardous" beliefs such as the one "church" where God is believed to have been a man before He "became" God, and where Father, Son and Holy Spirit are taught to be three different "gods," where Jesus is also a "brother" of Satan, who left additional "scriptures" on metal plates in Egyptian hieroglyphs in Pennsylvania, and we all become [real} Gods one day? We all know what "church" is that, don't we?
Or, why not be concerned about the ones who have the OT but reject Jesus Christ? After all is it more "spiritually hazardous" to be some sort of a Christian "even" Catholic and Orthodox (sarcasm) rather than a non-Christian?
And if Marian veneration is "idolatry" to you (Protestants), what is it to you? No one is forcing you to do the same!
Protestant preoccupation with Marian veneration is closer to bashing than to a concern. More importantly, it also misses the mark: like traffic cops being concerned with a car going 10 miles over the speed limit and letting bank robbers in the car next to it get away.
In other words, there are much more "spiritually hazardous" groups whose beliefs and practices should be the focus of Protestants' obessions than Marian devotion in the Catholic and Orthodox Churches.
faulty Mariology = faulty Christology; functionally, logically yields Mary = Jesus
Tell me, show me, where is that ever explicitly or implicitly stated in any Catholic/Orthodox doctrine. It "exists" only in some Protestant minds. No Catholic/Orthodox will ever say that Mary is divine or equal to Christ!
And if our Christology is wrong (Two natures, one divine and one human, fused but not confused, in one Person), then not only the Catholics and the Orthodox, but all the mainline Protestants and Baptists are in Christological error as well.
So, we know the objections regarding Marian devotion. Thank you (Protestants) for bringing it to our attention. Since no one is forcing you to believe it, leave it at that and be cocnerned with your own (Protestant) issues such as why the Presbyterians use musical instruments when the original Prebsyterians strictly forbade them (traditions of men maybe)?
Is think your (Protestants) real cocnerns of "spiritual hazards" should be focused on those groups that deny Christ is God, or that He died, or that He had a (real) body, or who preach that Mary Magdalene was His "wife/lover" and had children with Him, or that He was not really a man, but only appeared as such, or that He is a lesser God than the Father, etc.
Those are serious Chritologically "hazardous concerns" and Mary doesn't even enter the picture.
