Saying all that, it doesn't surprise me that that some Protestants who have no understanding of scripture and are not grounded in the Word of God would succumb to such pagan idolatry.
I might add that the website states "However, this article will attempt to skim the surface of these mysteries just a bit, so that you can appreciate this special devotion in a deeper theological way." It is astounding that one would try to explain "deeper theological" truths based upon the experiences and visions of others. They might as well join the Mormons.
