It follows that individuals, whether they be priests or lay faithful, are not free to add or subtract any details in the approved rites of the celebration of the Holy Eucharist (cf Sacrosanctum Concilium, 22). A do-it-yourself mentality, an attitude of nobody-will-tell-me-what-to-do, or a defiant sting of if-you-do-not-like-my-Mass-you-can-go-to-another-parish, is not only against sound theology and ecclesiology, but also offends against common sense. Unfortunately, sometimes common sense is not very common, when we see a priest ignoring liturgical rules and installing creativity – in his case personal idiosyncrasy – as the guide to the celebration of Holy Mass. Our faith guides us and our love of Jesus and of his Church safeguards us from taking such unwholesome liberties. Aware that we are only ministers, not masters of the mysteries of Christ (cf I Cor 4:1), we follow the approved liturgical books so that the people of God are respected and their faith nourished, and so that God is honoured and the Church is gradually being built up.
