Anyone who still harbours the slightest doubt need look no further than the works of corporal mortification that he is now known to have performed regularly.
Corporal mortification is an integral part of Catholic spirituality. Catholics need to re-learn moderate self-denial on Fridays, on the Wednesdays in Lent, during Holy Week, on the eves of the Church’s greatest Solemnities, and before receiving Communion, as well as the considerable exigencies on Ash Wednesday and Good Friday.
These are of a piece with the cilice (a spiked chain worn around the upper thigh) and the discipline (a small whip used on the back). Convents manufacturing such items still do a roaring trade, and the rise of Opus Dei is a sign that the decadent period of disdain for asceticism even within the Catholic Church is an aberration now mercifully coming to an end.
