Commemoration of Gilbert of Sempringham, Founder of the Gilbertine Order, 1189 Some there are who presume so far on their wits that they think themselves capable of measuring the whole nature of things by their intellect, in that they esteem all things true which they see, and false which they see not. Accordingly, in order that man's mind might be freed from this presumption, and seek the truth humbly, it was necessary that certain things far surpassing his intellect should be proposed to man by God.

He that obstinately denieth the truth before men upon earth, wilfully refuseth his soul's health in heaven.

Whatever a man has in superabundance is owed, of natural right, to the poor for their sustenance. So Ambrosius says, and it is also to be found in the Decretum Gratiani: The bread which you withhold belongs to the hungry: the clothing you shut away, to the naked: and the money you bury in the earth is the redemption and freedom of the penniless.

Nothing created has ever been able to fill the heart of man. God alone can fill it infinitely.

By the divine providence [animals] are intended for man's use... Hence it is not wrong for man to make use of them, either by killing or in any other way whatsoever.

Beware the man of a single book.

Even as he would be guilty of falsehood who would, in the name of another person, proffer things that are not committed to him, so too does a man incur the guilt of falsehood who, on the part of the Church, gives worship to God contrary to the manner established by the Church or divine authority, and according to ecclesiastical custom.

Just as in one man there is one soul and one body, yet many members; even so the Catholic Church is one body, having many members. The soul that quickens this body is the Holy Spirit; and therefore in the Creed after confessing our belief in the Holy Spirit, we are bid to believe in the Holy Catholic Church.

Man cannot live without joy; therefore when he is deprived of true spiritual joys it is necessary that he become addicted to carnal pleasures.
