While I do not agree with the simplistic nature of the above statement, there would be a big advantage to the Church. For one thing it would reduce the influence and activities of the gay bishops and clergy, add more priests that speak the English language, offset the young control-freaks who want to go back, back, back and encourage American heterosexual men to enter seminaries.
But there is a cost, which is not worth the advantage.
Priestly celibacy in the Western Church stands in stark opposition to the cult of sexuality in the West. A celibate priest proves that chaste life in complete dedication to God is fulfilling and possible and that control of our passions is possible. In the culture saturated with self-indulgence, priestly celibacy is of tremendous value to the laity today, more than ever before.
