Maybe more men would choose the priesthood, but the question is, “Would this be what is best for the Church?” As said above, celibacy for the sake of the Kingdom is a powerful sign that Jesus is real, and that He is worth living for, sacrificing for, and dying for! Besides, in the world as a whole, vocations to the priesthood and religious life have dramatically increased in the last thirty years.
In Africa they increased by 394%; in S.E. Asia by 152%; in Central America by 165%; and in South America by 253%! It is only in the U.S. and Western Europe that there has been a decline. Perhaps the problem is not celibacy, but other larger cultural issues and values.
