Doesn't it appear that the new precepts did away with rule number six (Concerning marriage) and they split rule number one into two.
Now I know the Church does allow a Catholic to marry a non Catholic - with certain stipulations a dispensations, - I should mention that the new prayer book has a whole section on the "Church Laws concerning marriage"- so the laws are duly noted) but still shouldn't obedience to these Church laws on marriage be listed somewhere in the precepts- you know the six very basic things you have to do to be in "the church."
I suggest the following:
1. You shall keep holy Sundays and Holy days of Obligation by attending Mass and abstaining from labours and business.
6. You shall marry in accordance to Church laws.
