The priest doesn’t just face the altar and liturgical east to symbolically lead the people, who face the same direction with him. He also stands between the altar and the people in part as intercessor, turning first to the altar, then to the people, then back to the altar again, fulfilling his function AS a priest.
Old, beautiful churches were designed with this in mind. When our church turned the altar around decades ago, the original Gothic high altar and reredos behind it were removed. A painting of the Virgin and saints above it was painted over, statues and the altar rail were removed, and the church interior looked like a glorified barn. A horizontal swath of pews was also removed to facilitate processions and an offering table was smacked down into the center of it all as the starting point for the ritual “schlep to the altar by stumbling laypeople bearing offerings”. (Now there’s talk of removing the kneelers!) Right around the same time, our nuns abandoned their blue-grey habits and graceful starched coronets, and took to wearing tacky lay clothes, moved from the convent to an apartment, took secular jobs, and got their hair done.
Some of us have asked our pastor for a Tridentine Mass, or even a more reverential Novus Ordo, but his head is stuck in the 60’s. Nice to know that some priests sense the value and historic continuity in ad orientem.
