Is it permissible for a non-cleric to make use the Fascia ( Sash on cassock) when serving at the Altar? I have only ever seen a non cleric wear it once, so I am not sure if it is allowed or not.
The traditional answer, I believe, would be no. Nainfa, in Costumes of Prelates of the Catholic Church (1909) at 57-60 states:
The cincture, belt, or sash (called fascia in Ceremonials and other Latin document), is for the Clergy a sign of jurisdiction, and for Prelates a mark of their dignity. . . .
Irremovable parish priests, as a sign of ordinary jurisdiction, and Rectors of Seminaries as a sign of authority, are privileged to wear a black cincture of plain silk with fringes at the bottom. . . .
Altar boys who, in liturgical functions, are permitted to perform the duties of clerics must wear the cassock and surplice; but the Sacred Congregation of Rites forbids them to wear a cincture.
