If you profess to be Catholic by attending Mass each Sunday, praying the Credo during Mass and receiving Jesus in the Most Blessed Sacrament then you should darn well be a believer in all Holy Mother Church teaches. This goes tripled for those who are in ministry in a parish (be it DRE, CRE, RCIA Director, the person in charge of the formation of the children in the Parish School of Religion…and so on.)
Many issues, such as an all male priesthood, were settled in the early days of the Church, we do not need to go and reinvent the wheel. If Jesus had wanted women to be priests, He would have done so when He called the 12. If you think about it, who was the one and only person ever to be born without Original Sin? His mother, our mother, the Blessed Virgin Mary. If anyone was worthy of priesthood, shouldn’t it be the one who was sinless and did the Will of God her entire life? However, she was not called. While this may not be the most theologically in depth argument, it does hold a lot of water.
The Catechism of the Catholic Church also addresses this issues. If you open your Catechism to number 1577, you will see:
Only a baptized man (vir) validly receives sacred ordination.”66 The Lord Jesus chose men (viri) to form the college of the twelve apostles, and the apostles did the same when they chose collaborators to succeed them in their ministry.67 The college of bishops, with whom the priests are united in the priesthood, makes the college of the twelve an ever-present and ever-active reality until Christ’s return. The Church recognizes herself to be bound by this choice made by the Lord himself. For this reason the ordination of women is not possible.68
Of course, this is all meaningless, unless you accept the teachings of Holy Mother Church through the guidance of the Holy Spirit. If that is the case, then why are you even in the position you are in? How can you work for an organization that you do not agree with?
