I doubt it would make much different considering our bishops, priests, and deacons already have the authority to declare two people legally married as a part of the wedding rite. It will take counter legislation, perhaps a constitutional amendment, to stop this attack by homosexuals not the Church changing its teachings on the sacrament of marriage. Otherwise, the Church has always been counter-cultural when the culture has defied or strayed from God’s law and suffered for it. Jesus promised us the world would persecute us, so we shouldn’t be surprised or even alarmed when it happens since life with Christ and his truth is worth it all.
