Details:
The procession is the first part of the mass. During a solemn Mass, the priest processes in from the narthex with deacon, and subdeacon, master of ceremonies and servers. During Low Mass, the priest processes in with alone or with one or two servers and places the veiled chalice on the centre of the altar and makes the sign of the cross at the foot of the altar. At Solemn Mass, the chalice is placed beforehand.
