Why are Polish so conservative and religious? [240]
Harry, have a look at this:
Question:
What does the Church say exactly about the Saturday evening Mass? - J.G., Arras, France
Answered by Legionary of Christ Father Edward McNamara, professor of liturgy at the Regina Apostolorum university.'The norms permitting the celebration of Sunday Mass on a Saturday evening are not overly detailed and thus different practices and notions have arisen around the world.
Even though this practice is relatively recent with respect to the Sunday Mass, the Church had long maintained the custom of beginning the celebration of important feasts the evening before, with first vespers. This was inspired by the concept of a day in the ancient world which divided our 24 hours into four nocturnal vigils and four daylight hours, the day commencing at first vigil.
The general law does not specify the precise time after which Sunday Mass is possible. However,
5 p.m. is the common rule in the Diocese of Rome and in many other places. Any time much earlier is hard to conceive as being Saturday evening in any meaningful sense of the term.'
