Those of us who do formation work are required to help sort out between deep seated homosexual tendencies and same-sex attraction. They are not the same thing.
I use this simple method, but it actually works. Our bodies do not know that our souls and minds are Catholic. Our libido may respond to members of either sex. This is an attraction. If it responds to your own sex, it’s a homosexual attraction and it it responds to the opposite sex, it’s heterosexual attraction.
A deep seated homosexual tendency is a little deeper, a lot deeper actually. The person identifies himself or herself in terms of their sexual attraction and organizes his mental constructs around them. Therefore, the person has difficulty establishing healthy relationships with both genders, but it alwasy drawn to be more attentive and intimate with one gender over the other. Even when the person is not actively havin sex, this difficulty establishing meaningful and respectful relationships with both genders makes him or her an unqualified candidate for the priesthood or religious life.
Though the Church has not written a formal declaration on the subject, we follow the same rule for the admission of heterosexuals to holy orders or to religious life. There are some heterosexual people who do lack a healthy affect. The best example that I can offer is the super macho. This is the man who has difficulties relating to women as equal partners in society and in the faith. Such a person may even tend to be homophobic. This person must also be disqualified from religious life or holy orders.
In essence, what we’re looking at when we study a candidate is for a well balanced personality capable of having meaningful relationships with both genders and capable of exercising discipline over his/her sexual responses to triggers. You cannot do away with the sexual triggers. That’s a given. But you must have the internal discipline to respond to them without a struggle. If these triggers create a struggle for the person, then the feelings can safely be deemed to be deep seated. In charity, we do not want to place anyone in a situation of greater struggle than what he already deals with in daily life.
I hope this helps.
