The Aparecida bishops aim to ordain a mature person:
321. Special attention must be devoted to the process of human formation toward maturity, so that the vocation to the ministerial priesthood of the candidates becomes in each of them a stable and definitive life project, in the midst of a culture that exalts the disposable and the provisional.
So, countercultural. But not sheltered in the sense of ignorance or running away from one’s emotions:
The same is true of education for affectivity and sexual maturity. Such maturity should lead to understanding better the gospel meaning of consecrated celibacy as a value that configures one to Jesus Christ, and hence as a state of love, fruit of the precious gift of divine grace, according to the example of the nuptial self-giving of the Son of God; to receiving it as such with firm decision, with magnanimity and wholeheartedly; and to living it with serenity and faithful perseverance, with proper ascesis on a personal and community journey, as surrender to God and to others with a full and undivided heart.(Cf. Presbyterorum Ordinis 16; Optatam Totius 4; Pastores Dabo Vobis 50; Congregation for the Clergy, Directory on the Ministry and Life of Priests; n.5; Congregation for Catholic Education, A Guide to Formation in Priestly Celibacy, n. 31, Rome 1974.)
In other words, one can’t give up what one has never had.
