The Church of Rome is the second and last place the first bishop Peter reigned after Antioch. From here the Latin Catholic Church began her proliferation across the world, crossing national boundaries while preserving national identity for peoples. How can this happen? What religion could accomplish this? We explain in two other posts (The Evangelization of Celibacy, The Fulcrum of the Kingdom of God) that this has everything to do with celibacy. The other Churches that came out of Antioch did not so emphasize celibacy for priests, religious, and laity and evolved into Churches of national associations but with intact Sacraments. Sources of sacramental graces for millions of peoples and families but with a limited international reach compared to the Latin Church, except when those families migrated.
The premise in western cultures that sexual activity is some sort of necessary evil with only marginal potential for something of beauty has many origins but one can point out the writings of Sigmund Freud, a drug addict and pervert, as one source. The foundation of every psychology department all over the world. We have no control over these urges. Some sort of compromise has to be worked out with our sexuality. But this is not so. This has been permanently changed with the eternal work of Jesus, God and man, and His mother, the Mother of God. The Hearts of the new nature of mankind has been established. The particulars of this eternal event are wholly dependent on you and I.
So worked out for us here, celibacy not only becomes an attainable option, but the practical means for the evangelization of peoples. Without it, the Church of Rome will be reduced to the Church of Italy, or some other geographic boundary.
