Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
Think not that I am come to destroy the Law, or the Prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
(ubi sup.) Or, the precepts of the Law are called ‘the least,’ as opposed to Christ’s precepts which are great. The least commandments are signified by the iota and the point. He, therefore, who breaks them, and teaches men so, that is, to do as he does, shall be called least in the kingdom of heaven. Hence we may perhaps conclude, that it is not true that there shall none be there except they be great.
