"Keep this in mind, my brothers; practice it and preach it with in a gentle manner that shall never fail. Love the persons you oppose, and kill only their lies. Rest on truth; defend it, but without cruelty. Pray for those whom you oppose; pray for them while you correct them."What applied to the evangelization of ancient heretics, schismatics, Jews, and pagans in St. Augustine's time applies to the evangelization of heretics, schismatics, non-Christians and pagans, and those who have no faith at all today. This includes those within the Roman Catholic Church greatly opposed to the hermeneutic of continuity!
St. Augustine was a bishop with some entrenched opposition in his territory, notably the Donatists. So he was no stranger to protracted battles of belief and ritual. We'd do well to remember 1 Corinthians 13. And let me state that this isn't an accusation. We're just all called to holiness. Tradition won't be fully revived if we're jerks about it. And, Our Lord will say to us, "I do not know thee. Depart from me," on the Judgment Day.
Also, from the bishop of Hippo:
"For he who sings praise, does not only praise, but also praises joyfully; he who sings praise, not only sings, but also loves Him whom he is singing about.” - St. AugustineSing the sacred liturgy. Chant and the liturgy are woven together!
