I have been alerted to these videos from gloria.tv of His Excellency Most Rev. Malcolm Ranjith, Secretary of the Cong. for Divine Worship and Discipline of the Sacraments.
One of them concerns the use of Latin as a sacred language for the Latin Rite.
He mentions false understanding of "active participation" and Communion in the hand, Mass as mere "celebration". He warns against the attitude that just because a liturgical practice is old, or ancient, it is there best.
He talks about Pope Benedict’s purposes for issuing Summorum Pontificum, connecting his motive to salus animarum suprema lex, the supreme law of the Church is the salvation of souls.
Do it yourself liturgy. He compares abusive creativity or the imposition of personal preferences, which are "disastrous", as making oneself like God.
He also obliterates the false claim that "because Jesus faced the apostles at the Last Supper, we should have Mass facing the people". In the ancient world, people reclined to eat, facing more or less the same direction with their couches arranged in a "U".
You might enjoy these.
