To a priest who learned the Traditional Mass and then quit because it was hard.

Many priests have related to me about how, once they learned, or relearned it, their sense of themselves as priests, as priests at the altar, as priest victim, as priest redeemed sinner has ever after exercised its influence over how they work and act, especially in their ars celebrandi. In turn, this creates a slow but inexorable knock-on effect in their congregations.
