The Second Vatican Council, especially in the Constitution on the Sacred Liturgy, repeatedly drawing upon tradition called attention to Christ's Paschal Mystery and pointed out that it is the font from which all sacraments and sacramentals draw their power. ... Without a doubt one of the principal reasons [there are errors in the celebrations of the Triduum] is the inadequate formation given to the clergy and the faithful regarding the Paschal Mystery as the center of the liturgical year and of Christian life. ... It is the aim of this document that the great mystery of our redemption be celebrated in the best possible way so that the faithful may participate in it with ever greater spiritual advantage.
