The desire is thy prayers; and if thy desire is without ceasing, thy prayer will also be without ceasing. The continuance of your longing is the continuance of your prayer.
Saint AugustineOften a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances... and this knowledge he holds with certainty from reason and experience. It is thus offensive and disgraceful for an unbeliever to hear a Christian talk nonsense about such things, claiming that what he is saying is based in Scripture. We should do all that we can to avoid such an embarrassing situation, which people see as ignorance in the Christian and laugh to scorn.
Saint AugustineAs to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
Saint AugustineThey who shall enter into [the] joy [of the Lord] shall know what is going on outside in the outer darkness. . .The saints'. . . knowledge, which shall be great, shall keep them acquainted. . .with the eternal sufferings of the lost.
