The fact that the Church ordains some married men demonstrates that it is considered, and indeed done. However, allowing clergy to marry following ordination cannot be done: a priest is not the proper matter for the Sacrament of Matrimony, so there would be no valid marriage. Clergy living in fornication relationships is a bad idea.
I’m just a humble suburban breeder, myself. One needn’t be an ecclesiastical scholar, just literate and interested, in order to read the Catechism of the Catholic Church.
I still don’t understand why a priest cannot be a priest and afterward get married. As long as it’s a loving, monogamous,heterosexual relationship blessed by the Church through the Sacrament of Marriage, what’s the problem? And as long as the priest continues to discharge the duties of his holy calling, what’s the problem? Surely any problems or scandals ensuing would pale in comparison to the those the Church is currently experiencing. Any scandals would at least involve consensual adults rather than innocent children.
