No ... but you are making a judgment call. Catholic priests, regardless of their orientation, take a vow of celibacy. It has been this way for more than 1000 years. Celibacy is a discipline. For those properly disposed, it is a personal and joyous gift to God.
As for ridding the seminaries of homosexuals, there is a review board currently evaluating each and every seminary in the US. One of its goals is to scrutinize seminarians and applicants to ensure that those "not properly disposed" are turned away, regardless of their orientation.
It ha been that way for a long time but not since the begining.
Everyone SHOULD take that vow seriously whether they think it's right they had to take it or not, however there is an epidemic of homosexuals within the church, and the churches are losing parishioners because they no longer trust the clergy.
I think allowing men who have married but who now feel a call to the priesthood to join would help to convey to parishioners that the same values they hold with regard to family, are held by the priest, and reassure them the priest is not a wolf in sheeps clothing.
Further it would be in line with ancient tradition.
Further scrutinization will lead to less wolves in priest clothing but it will reduce the number of the priestshood and put preassure to reduce the number of churches. It also doesn't do a whole let to reassure parishioners in individual churches. It won't help stem the tide of those not attending because they cannot trust the clergy.
I think that allowing married men, who've suitably proven themselves to be fit for the priestshood to enter into it would be much more reassuring, and in keeping with ancient tradition.
