Now you could argue that Catholic priests are not doing this so much as positioning themselves as representatives of the Heavenly Father, such as for doing things like receiving confessions and the like
A Catholic, or Orthodox priest is called "Father." They do not take this title upon themselves, they are given it. And when operating AS priests, they stand IN PERSONA CHRISTI, which means that they represent the Son, and not the Father. If you are going to dump on Catholics, at least know the correct doctrine first.
And before you go any farther, the Catholic Church, in union with ALL Christianity, does NOT worship Mary or the saints. It is expressly taught AGAINST!
"
All generations will call me blessed": "The Church's devotion to the Blessed Virgin is intrinsic to Christian worship." The Church rightly honors "the Blessed Virgin with special devotion. From the most ancient times the Blessed Virgin has been honored with the title of 'Mother of God,' to whose protection the faithful fly in all their dangers and needs. . . . This very special devotion . . . differs essentially from the adoration which is given to the incarnate Word and equally to the Father and the Holy Spirit, and greatly fosters this adoration." The liturgical feasts dedicated to the Mother of God and Marian prayer, such as the rosary, an "epitome of the whole Gospel," express this devotion to the Virgin Mary.
Note: it says devotion to, not worship of. Being a good Christian, I would guess that you were devoted to your mother, and if she is still alive, you remain devoted to her, doing the little things she can't do any more. My mother died about fifteen years ago. All her life she treated me as a disposable work unit, and nothing more. But I still love her, and miss her.
Just so, Catholics are devoted to Mary. We do not worship her. It goes against the Catholic faith to worship Mary or any of the saints, and if you think I'm mistaken, wrong, "missing God's will for my life," or anything else, then you are totally off point, and maybe you're not listening to the Holy Spirit as close as you THINK you are.
