[quote=joshua1]I think it is somewhere in the Bible that we are called to a royal priesthood.
Indeed it does, and that is why the Catechism of the Catholic Church teaches that all members of the Catholic Church are priests.**Catechism of the Catholic Church
THE GRACE OF BAPTISM
1268** The baptized … share in the priesthood of Christ, in his prophetic and royal mission. … Baptism gives a share in the common priesthood of all believers.[indent]… let yourselves be built into a spiritual house to be a holy priesthood to offer spiritual sacrifices acceptable to God through Jesus Christ
1 Pet 2:5.
… you are "a chosen race, a royal priesthood, a holy nation …”
1 Pet 2:9.**THE SACRAMENT OF HOLY ORDERS
The one priesthood of Christ (1544 & 1545)
Two participations in the one priesthood of Christ
1546** Christ, high priest and unique mediator, has made of the Church “a kingdom, priests for his God and Father.” The whole community of believers is, as such, priestly. The faithful exercise their baptismal priesthood through their participation, each according to his own vocation, in Christ’s mission as priest, prophet, and king. Through the sacraments of Baptism and Confirmation the faithful are “consecrated to be . . . a holy priesthood.”
1547 The ministerial or hierarchical priesthood of bishops and priests, and the common priesthood of all the faithful participate, “each in its own proper way, in the one priesthood of Christ.” While being “ordered one to another,” they differ essentially. In what sense? While the common priesthood of the faithful is exercised by the unfolding of baptismal grace --a life of faith, hope, and charity, a life according to the Spirit–, the ministerial priesthood is at the service of the common priesthood.[/indent]
To say Mary confected the Eucharist is Heresy with a capital H.
Yes, that would be heresy, but that doesn’t change the fact that Mary is a priest in the Catholic Church. The question has been raised if we can conceive of Mary as a priest. The answer to this is, yes, Mary is a priest because Mary is part of a nation of priests.
