Here are some excerpts.
By his sacrifice on the cross, Christ is the unique high priest, the mediator between God and humanity. This priesthood of Christ is made present in our lives through the priesthood, which serves as an “icon” – or representative – of Christ in the world.Read the whole thing
The call to the ministerial priesthood comes from God and is authenticated by the Church, not by any individual. Holy Orders is a gift that those called do not earn, deserve, or have as a right. The call to ordination is received unmerited through the grace of God.
Holy Orders is the sacrament through which the mission entrusted by Christ to his apostles continues to be exercised in the Church until the end of time. It is the sacrament of apostolic ministry and it is through the bishops, the successors of the apostles, that this gift of God is passed on from generation to generation through ordination.
As apostolic succession represents the living presence of the apostles in the Church until Christ’s return, and the priest serves as an icon or representative of Christ’s sacramental presence in the Church, the Church must conform to the delegation made by the Lord.
The ordination of males to the priesthood is not merely a matter of practice or discipline within the Church. Rather, the Church has determined that this is part of the Deposit of Faith handed down by Christ through his apostles. The Church is therefore bound by it and not free to change in this regard.
Ordination to the priesthood must be conferred by an ordained bishop on a baptized man. A candidate must receive the blessing of the Church, which has the authority and responsibility to determine if a true call to the priesthood exists.
This unfortunate ceremony will take place outside the Church and undermines the unity of the Church. Those attempting to confer Holy Orders have, by their own actions, removed themselves from the Church, as have those who present themselves for such an invalid ritual. Additionally, those who by their presence give witness and encouragement to this fundamental break with the unity of the People of God place themselves outside the Church.
