A Christian man is on his guard with respect to those who philosophize according to the elements of this world, not according to God, by Whom the world itself was made; for he is warned by the precept of the apostle and faithfully hears what has been said, 'Beware that no one deceive you through philosophy and vain deceit, according to the elements of the world'
Saint AugustineTwo loves have made two different cities: self-love hath made a terrestrial city, which rises in contempt of God; and Divine Love hath made a celestial one, which rises in contempt of self. The former glories in itself - the latter in God.
Saint AugustineThe Church even now is the kingdom of Christ and the kingdom of heaven. Accordingly, even now His saints reign with Him, though otherwise than as they shall reign hereafter; and yet, though the tares grow in the Church along with the wheat, they do not reign with Him. For they reign with Him who do what the apostle says, 'If you are risen with Christ, mind the things which are above, where Christ sits at the right hand of God. Seek those things which are above, not the things which are on the earth'.
