The truth is that Catholics do *not* worship Mary (thus making her equal to God) but give her the highest honor among saints due to her being the mother of Jesus Christ. Therefore, her interceding in prayer is greatly sought by the faithful.
Praying for others is not exclusive to Catholics. Non-Catholic Christians do likewise, except that they do not pary for the souls of the dead.
"...they do not pary for the souls of the dead."
I meant "pray", not "pary".
