My question is if mass is celebrated by a priest and a deacon, and the priest lets the deacon distribute holy communion from the chalice which was removed from the tabernacle, is the priest allowed to purified the other vessels and the alter while the deacon distributes communion? The reason I’m asking I have never witness this happening before in the 58 years I have been Catholic. As per the Vatican website it is suppose to be done after communion or after mass. Is this open for interpretation?
CONGREGATION FOR DIVINE WORSHIP
AND THE DISCIPLINE OF THE SACRAMENT
CERTAIN OTHER MATTERS CONCERNING
( section 3 Sacred Vessels, paragraph 119 & 279)
[119.] [119.] The Priest, once he has returned to the altar after the distribution of Communion, standing at the altar or at the credence table, purifies the paten or ciborium over the chalice, then purifies the chalice in accordance with the prescriptions of the Missal and wipes the chalice with the purificator. Where a Deacon is present, he returns with the Priest to the altar and purifies the vessels. It is permissible, however, especially if there are several vessels to be purified, to leave them, covered as may be appropriate, on a corporal on the altar or on the credence table, and for them to be purified by the Priest or Deacon immediately after Mass once the people have been dismissed.
"279. The sacred vessels are purified by the Priest, the Deacon, or an instituted acolyte after Communion or after Mass
