you may have heard a rosary before or after Mass but NEVER during a Mass. Unless she is mentioned in a reading such as during the season of Christmas, Mary is mentioned only once in a regular Mass and that is during the confetior when we ask her , along with the parishioners, to pray for us.
The Eucharist in the Catholic church is not the same as communion in your church....The Catholic Eucharist is actually the presence of Christ under the appearance of bread and wine whereas your church teaches it as a mere remembrance ceremony.
As Christ said..."do this in remembrance of Me."
