When does the Triduum begin and end?
The Easter Triduum begins with the evening Mass of the Lord’s Supper on Holy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. May another Mass besides the Mass of the Lord’s Supper be celebrated on Holy Thursday? Ordinarily, no other Mass may be celebrated on Holy Thursday. However, by way of exception, the local Ordinary may permit another Mass in churches and oratories to be celebrated in the evening, and, in the case of genuine necessity, even in the morning. Such Masses are provided for those who in no way are able to participate in the evening Mass. How are the Holy Oils, consecrated and blessed at the Chrism Mass, to be received in the parish? A reception of the oils may take place at the Mass of the Lord’s Supper. The oils, in suitable vessels, are carried in the procession of the gifts, before the bread and wine by members of the assembly. A text for this can be found in the 2004 Sacramentary Supplement published by Catholic
