Those who are not good to others are bad to themselves.

Truth, which is simple and one, admits of no variety.

I have neither permitted, nor shall I permit, the things which have been settled by the holy fathers to be violated by any innovation.

... the Apostle says, 'he that says he abides in Christ ought himself also to walk as He walked' (I Jn. 2:6). Otherwise we make a vain pretence and show, if we follow not His steps, Whose name we glory in, and assuredly they would not be irksome to us, but would free us from all dangers, if we loved nothing but what He commanded us to love.

The Church is a virgin, the bride of one Spouse, Who is Christ, and this Church does not allow herself to be violated by any error; so that, throughout the whole world there may be for us one uncorruptedness of a single chaste communion.

The birthday of the Lord is the birthday of peace.

The devil is always discovering something novel against the truth.
