I came across this from St. Augustine:
St. Augustine writeth thus: “We dedicate and consecrate the memory of God’s benefits with solemnities on solemn appointed days, lest in process of time they might creep into ungrateful and unkind oblivion.”
And of the martyrs thus: “Christian people celebrate the memories of martyrs with religious solemnity, both to move themselves to an imitation of their virtues, and that they may be partakers of their merits, and helped by their prayers.” (Conta Faust. lib. xx. chap. 21.)
And of other saints thus: “keep ye and celebrate with sobriety the nativity of saints, that we may imitate them that are gone before us, and that they may rejoice in us, who pray for us.” (In Ps. lxxxviii. Conc. 2. in fine.)
Is St. Paul constantly telling people to leave the old ways behind?
