In that case the celebrant stood behind the altar at mass, and looked over it eastwards towards the people.
Hitherto the chasuble had been worn indifferently by all ministers at the eucharist, even by the acolytes; it had been worn also at processions and other non-liturgical functions; it was now exalted into the mass vestment par excellence, worn by the celebrant only, or by his immediate assistants (deacon and subdeacon) only on very special occasions.
On Easter Sunday the queen ventured to display her personal preference for the Protestant conception of the eucharist by forbidding the celebrant in her chapel to elevate the host.
The object of the change was primarily to leave the hands of the celebrant freer for the careful performance of the manual acts, and to this end a process of cutting away at the sides of the vestment began, which continued until the tent-shaped chasuble of the 12th century had developed in the 16th into the scapular-like vestment at present in use.
Whenever a bishop was celebrant he was to wear, "beside his rochette, a surplice or albe, and a cope or vestment," and also to carry " his pastoral staff in his hand, or else borne or holden by his chaplain."
