That link is actually a pretty wild ride. Excerpt: "Father Jerome of Texo, of the Society of Jesus, rejoiced in the name of slave of Mary; and, as a mark of servitude, went often to visit her in some church dedicated in her honor. On reaching the church, he poured out abundant tears of tenderness and love for Mary; then prostrating, he licked and rubbed the pavement with his tongue and face, kissing it a thousand times, because it was the house of his beloved Lady".
If I recall correctly the bible said not to worship the idols themselves or other gods through idols.
The way many orthodox christians interpret this is that it's ok to have religious symbols or icons as long as you use them as tools of worship and not worship them.
