"The point is the priest's presence in the Divine space is in conflict with the purpose of marriage, -- which is to restore a proximity to the Divine space of the Garden where the three-way communion between man, woman and God was intact."
Nonsense. Marriage is the first Covenantal union between man, woman and God which has been raised to the status of a Sacrament by Christ.
Adam was THE FIRST PRIEST and prior to the fall, the priest par excellence, and he was so at the same time as which he was married. There is no theological conflict between priesthood and marriage whatsoever. To suggest that there is a conflict is a heresy, as it is a denial of the inerrancy of both Holy Scripture and Holy Tradition.
In #74 and #76 you can see where the Church, from Leo the Great to John Paul II saw a deep contradiction between priesthood and marriage.
What sacrifice did Adam offer? Understand that priesthood is meaningless before the Fall.
