Um, please note my 2 verbal comments above, especially the 2nd comment.
A picture can however speak louder than words.
I’ve been a part of FR and the religious threads now for many years, and am hardly a troll.
So, is it the statues of Mary inside Catholic churches that you believe cross the line into worship? Catholics have statues Joseph and various other Saints as well. I can’t see how statues of Mary would cross the line, since there are plenty of other statues dedicated to other important figures in Christianity.
Is it the Hail Mary, and the rosary? Well, Catholics have hundreds of prayers that are oriented toward many different important figures, included Archangels, Joseph, and every Saint. Mary just happens to be one of the most important of those figures, according to the belief in the immaculate conception. I don’t see how this crosses the line, either.
Every argument you use to say that the honoring of Mary crosses the line fails because Catholics do the same thing for Archangels, Saints, and other important Christian persons.
