161 Thus, the liturgical year should be considered as a splendid hymn of praise offered to the heavenly Father by the Christian family through Jesus, their perpetual Mediator.

It requires a serious effort and constant practice to imitate His mysteries, to enter willingly upon His path of sorrow and thus finally share His glory and eternal happiness.
