Council of Trent: Session XXV, On Choice Of Meats; On Fasts, And Festival Days

ON CHOICE OF MEATS; ON FASTS, AND FESTIVAL DAYS.

The holy Synod furthermore exhorts, and, by the most holy advent of our Lord and Saviour, conjures all pastors, that, like good soldiers, they sedulously recommend to all the faithful all those things which the holy Roman Church, the mother and mistress of all churches, has ordained, as also those things which, as well in this Council, as in the other oecumenical Councils, have been ordained, and to use all diligence that they be observant of all thereof, and especially of those which tend to mortify the flesh, such as the choice of meats, and fasts ; as also those which serve to promote piety, such as the devout and religious celebration of festival days; often admonishing the people to obey those set over them (Heb. xiii. 17), whom they who hear, shall hear God as a rewarder, whereas they who contemn them, shall feel God himself as an avenger.
