The Catholic Church teaches that while homosexual tendencies or same sex attractions are “disordered” in the sense of desiring sex with a person of the same sex (not same sex intimate friendships that exclude sex, that is non-sexual love) we do not teach that merely having same sex attractions are sinful. It is sex outside of God’s recognized lawful marriage that is sinful. This applies equally to those who are heterosexual as well as homosexual. There is no double standard.
But with that said, when a person who is married commits adultery or when a single person, homosexual or heterosexual sins sexually, these sins can be forgiven and are forgiven in the Sacrament of Penance when one is truly sorry, repents, confesses and does penance. It isn't too difficult to receive God's Divine Mercy. In fact he places his grace in our hearts that leads us to Confession.
Most of our Catholic schools hire both Catholic and non Catholic teachers,but we expect them not to publicly in any way call into question or demonstrate a lifestyle opposed to the Church teaching on chastity. So for example if a teacher at at a Catholic School who is heterosexual desires to move in with her boyfriend and that becomes widely known, that would jeopardize that person’s job. It has nothing to do with her being a heterosexual, but it does have everything to do with her ability to model a chaste life to our students where Catholic education promotes chastity. As a single person how can you teach chastity in a Catholic Schools whose mission of course is to teach Catholic sexual morality if you are publicly living with another person in a sexual relationship?
Of course God teaches and the Church hands His teaching on that marriage is between one man and one woman and for a lifetime. That will never change in the Catholic Church. The gay lobby hates the Catholic Church for this and wants to do everything in its power to challenge and change the Catholic Church. Even the court system has ideologues that want to change the Catholic Church. Even the President of the United States wants to change the Catholic Church's teaching on the sanctity of life and marriage. I’m willing to be a martyr in opposing the gay lobby in this. Tell them to butt out! They hate the Catholic Church! They call her archaic (which of course our teachings are, they go back to God and eternity! These go back before Moses!)
For someone teaching in our schools they should understand and know that the bishop of our diocese who is the ultimate authority in protecting and promoting Catholic identity of Catholic institutions in our diocese has the final say and gives the ultimate direction to those who work in our diocese and even administrators. If a Catholic school opposed the bishop in this, the Bishop would have to take away that Catholic school's Catholic mission and identity. They would become a non-sectarian school or affiliate with another religious institution. They could not even have a Catholic chapel in that school.
A Catholic bishop must not allow any of the Sacraments of the Church to be mocked by anyone working in our schools. Marriage in one of the Catholic Church 's 7 sacraments and the one that is under siege by those who hate the Catholic Church’s teaching on sex and marriage. Same sex marriage is a mockery of the Church’s Sacrament of Marriage, pure and simple.
For example, I am sure that most of the non-Catholic teachers in our Catholic schools more than likely do not believe what the Catholic Church teaches about the Sacrament of the Most Holy Eucharist. That is fine as long as they keep it to themselves. In fact non-Catholics are not allowed by Church law to receive Holy Communion. If the administration of a Catholic school said, yes, you can receive Holy Communion at our school's Masses, no matter what the administration said, a Catholic bishop and local priests would have to say, no you can’t!
But let’s say that on their own a non-Catholic feels she has a right in our Catholic school and Church to receive Holy Communion, and does so in a very public way, that would be grounds for dismissing that faculty person, no matter what their personal beliefs are. Or let’s say that the non-Catholic makes known to her students in our school that her belief about Holy Communion which differs greatly from the Catholic Church’s belief is just as good as the Catholic Church’s belief and if students in that Catholic school agree with him, they should stand up for what they believe in contradiction of the Catholic Church even on school property, I would say that person should be fired on the spot.
Now let’s talk about proselytizing which can be defined as recruiting someone to join one's party, institution, or cause. This can be done actively or passively. It can be done intentionally or unintentionally. When someone who works in a Catholic school publicly supports same sex marriage and publicly gets married in a state that allows same sex marriage and makes it known they are gay, support the gay political agenda concerning marriage and want to propagate that by their own lifestyle and do so in a Catholic institution—that is called proselytizing pure and simple. Then when that person tells our students in our Catholic Church School to stand up for what they believe (even if it goes against the Catholic Church and to do it at a Catholic school) then Houston, we have major, major, major problems.
All of us are called to chastity. For the married person, lawfully married in the eyes of God as the Catholic Church teaches what lawful marriage is, chastity is fidelity to one’s spouse. For those who are not married, it means abstaining from sexual relationships, no matter if you are homosexual or heterosexual. There is no double standard. Ultimately as Catholics we must follow God’s law and oppose anyone trying to force the Catholic Church to follow laws that are contrary to God’s laws in the areas of sex and marriage. Pope Francis, oddly enough, on Thursday said that today Catholics must be willing to die as martyrs for the Catholic Church. He said we should go to our martyrdom as to a wedding banquet! Are you ready to stand up for the Catholic Church and to go to your martyrdom as to a wedding feast?
