Sacrosanctum Concilium

Rightly, then, the liturgy is considered as an exercise of the priestly office of Jesus Christ. In the liturgy the sanctification of the man is signified by signs perceptible to the senses, and is effected in a way which corresponds with each of these signs;

- Second Vatican Council, Constitution on the Sacred Liturgy Sacrosanctum Concilium (4 December 1963), §7, at The Holy See, www.vatican.va.

In quote from section 7 of SC we see reflected the sacramental character of the liturgy itself. I take this to be a reflection of the Canons from Trent session 22 cited earlier, though I need to demonstrate why I think that.

This pertains to sacramentals because like the liturgy they are instituted by the church to dispose men to and to actually impart the fruits of Christ's sacrifice. Or as it says earlier in section 7, to sanctify men and give glory to God.
