I've been told by experienced priests that it's best to have adult and boy altar servers together. Otherwise the boys often see Catholicism as a childish thing they must put aside with other childish things when their childhood is over. The idea grows that religion is for women and children, not for "real" men. Quite a mistake to make, after all.
What is most needed is a MALE Catholic education primarily for young men. Women's education is vastly easier to accomplish. Men's education is the great challenge that can turn everything around.
And it's the FRANCISCANS who should be the ones to carry the brunt of this hard work. Then Benedictines would provide a stable base and Dominicans do the preaching, but FRANCISCANS need to do the HEAVY lifting for MEN'S Catholic education. And the Franciscans need to be like dead men to this world and fight to the death against the prevailing anti-intellectual, provincial (i.e., barbaric) mindset that is actually one and the same with Feminism. Feminism and Rambo redneck idiocy are nothing but the two sides of exactly the same Jansenist & Anabaptist mindset of heresy & apostasy.
We have our work cut out for us. REAL men's Catholic education is where the war is won and lost. Time to begin winning that war for a change...
In particular, Benedictines and Franciscans have vast labours to achieve. We need to focus primarily on them, be ambitious for God (& His People & Church) and not overly nice to our fellow males of the species. When men take holy pride in being men they will see the desirability of entering into the Roman Catholic clergy. Especially Benedictine and Franciscan clergy.
Continued comment:
Absolutely right that virtually all the adult men (unless some actual physical or mental weakness prevents them) should be actively serving Mass! Then the boys would simply tag along in order to become real men. The focus among altar servers should be on men, and only secondarily on boys.
AND Catholic men should use that as a basis for an on-going interest in the education of young men (and sometimes older men too). There is another ingredient in this however. The men also require a military spirit. Not Keystone Cop running around with guns and knives, but more an actual sense of Knighthood among us. The men's education needs to have a military focus, again not superfluous weaponry but actually a real sense of nobility and Catholic aristocracy. Basically we're all nobles now and the Mass of 1962 (and Breviary of 1961) are key to realising this truth.
We should train virtually all the young men to be noblemen. Literally and with appropriate holy pride and (as Catholic warriors) even holy warrior arrogance towards the enemies of God. We men are not called to be overly "nice". We absolutely need the Catholic women for that; they can be good at niceness whereas we Catholic men never will be. We should be strong, courteous and a little nice, but not too much.
Also men's education must always fully include training in vocational work skills. Financial stability is always key for male innocence in future and all Catholic men should be innocent men. No difference between Catholic clergymen and laymen there.
We need to go seriously whole hog with this.
