The people will have no need to change their place of concourse; where of old they were wont to sacrifice cattle to demons, thither let them continue to resort on the day of the Saint to whom the Church is dedicated, and slay their beasts, no longer as a sacrifice to demons, but for a social meal in honour of Him whom they now worship.
Pope Gregory IThe holy universal Church teaches that it is not possible to worship God truly except in Her and asserts that all who are outside of Her will not be saved.
Pope Gregory IBecause He moves against faults, God is said to be angered, although He is moved by no disturbance of equanimity.
Pope Gregory IWhatsoever then you have well in this world, when you recollect to have done any thing good, be very fearful about it, lest the prosperity granted you be your recompense for the same good. And when you behold poor men doing any thing blameably, fear not, seeing that perhaps those whom the remains of the slightest iniquity defiles, the fire of honesty cleanses.
Pope Gregory I
