Our Holy Father, Pope Francis, has just this week published a new Apostolic Letter entitled DESIDERIO DESIDERAVI, a title which quotes Luke 22:15, Jesus saying: ‘I have earnestly desired to celebrate this Passover with you.’.
The letter addresses the subject of the Liturgical Formation of the People of God. From just a cursory reading, I can see it has many gems of insight and wisdom. It can be found in full at: https://www.vatican.va/content/francesco/en/apost_letters/documents/20220629-lettera-ap-desiderio-desideravi.html
