Mary has already stated she is the Immaculate Conception. Ignore all the miracles at Lourdes if you must. Block them out of your head and your ears. Cover up you ability to reason. In the end, I dont really care how you worship, though. I just loathe the attacks on Mary, the sinless mother of God.Whatever appeared at Lourdes was not Mary.
2 Corinthians 11:14-15 And no wonder, for even Satan disguises himself as an angel of light. So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds.
