"One change, never mentioned by Vatican II, was having the priest as a 'presider' face the people all through the Mass. It came at a time when people were increasingly preoccupied with themselves, and it encouraged a psychology of self-absorption. The venerable 'ad orientem' posture of the priest, always kept in the Eastern rites, is not a matter of turning his back to the people. Rather, the priest faces East to direct the faithful’s attention away from himself and toward the horizon symbolizing the Resurrection."
So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter (2 Thess. 2:15). Guard what has been entrusted to you. Avoid the godless chatter and contradictions of what is falsely called knowledge, for by professing it some have missed the mark as regards faith (1 Tim. 6:21-22).
