What is the Holy Mass?

"At the Last Supper, on the night when He was betrayed, our Saviour instituted the Eucharistic sacrifice of His Body and Blood. This He did in order to perpetuate the sacrifice of the Cross throughout the centuries until He should come again, and so to entrust to His beloved spouse, the Church, a memorial of His death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a paschal banquet in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us.”

- from the Second Vatican Ecumencial Council’s Constitution on the Sacred Liturgy Sacrosanctum Concilium, n. 47

The Holy Mass is the sacrifice in which the Lord Jesus Christ, through the ministry of the priest, offers Himself to God the Father in an un-bloody manner, under the appearances of bread and wine, for the salvation of our souls.
