It was my belief that only ordinary ministers were supposed to purify the vessels and, unless there is an extenuating circumstance, consume the remaining blood. This was a terrible position for you to be placed in, espically in light of the amount remaining and the accidents of the Blood of our dear Lord.
From Redemptionis Sacramentum
[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. *Moreover a duly instituted acolyte assists the Priest or Deacon in purifying and arranging the sacred vessels either at the altar or the credence table. *In the absence of a Deacon, a duly instituted acolyte carries the sacred vessels to the credence table and there purifies, wipes and arranges them in the usual way.*209]
Perhaps if the pastor were to purify the vessels himself, he would become aware of the need to consecrate less.
God bless!
