Mateus 18
Glossa Ordinaria
Mateus 18:3-4
[(as quoted by Aquinas, AD 1274)] (interlin.) Except ye be converted from this ambition and jealousy in which you are at present, and become all of you as innocent and humble in disposition as you are weak, in your years, ye shall not enter into the kingdom of heaven; and since there is none other road to enter in, whoso shall humble himself as this little child, the same is greatest in the kingdom of heaven; for by how much a man is humble now, by so much shall he be exalted in the kingdom of heaven. — Catena Aurea by Aquinas
Mateus 18:7
[(as quoted by Aquinas, AD 1274)] (non occ.) The Lord had said, that it is better for him who gives offence, that a mill-stone be hanged about his neck, of which He now subjoins the reason, Woe unto the world from offences! i. e. because of offences. (interlin. 1 Cor. 11:19.) Or they must needs come because they are necessary, that is, useful, that by this mean they that are approved may be made manifest. — Catena Aurea by Aquinas
Mateus 18:10
[(as quoted by Aquinas, AD 1274)] (ap. Anselm.) Or otherwise; Because so great evils come of brethren being scandalized, Take heed that ye despise not one of these little ones. (ap. Anselm.) Therefore are they not to be despised for that they are so dear to God, that Angels are deputed to be their guardians; For I say unto you, that in heaven their Angels do always behold the face of my Father which is in heaven. — Catena Aurea by Aquinas
Mateus 18:16
[(as quoted by Aquinas, AD 1274)] (ap. Anselm.) Or, that if he affirm that it is no trespass, that they may prove to him that it is a trespass. — Catena Aurea by Aquinas
Mateus 18:17
[(as quoted by Aquinas, AD 1274)] (ap. Anselm.) Or, tell it to the whole Church, that his infamy may be the greater. After all these things follows excommunication, which ought to be inflicted by the mouth of the Church, that is, by the Priest, and when he excommunicates, the whole Church works with him; as it follows, And if he will not hear the Church, let him by unto thee as an heathen, and a publican. — Catena Aurea by Aquinas
Mateus 18:19-20
[(as quoted by Aquinas, AD 1274)] (ap. Anselm.) But He holds out a ratification not only of sentences of excommunication, but of every petition which is offered by men holding together in the unity of the Church; for He adds, Again I say unto you, that if two of you shall agree upon earth, whether in admitting a penitent, or casting out a forward person, touching any thing which they shall ask, any thing, that is, that is not against the unity of the Church, it shall be done for them by my Father which is in heaven. By saying, which is in heaven, He points Him out as above all, and therefore able to fulfil all that shall be asked of Him. Or, He is in the heavens, that is, with saints, proof enough that whatever worthy thing they shall ask shall be done unto them, because they have with them Him of whom they ask. For this cause is the sentence of those that agree together ratified, because God dwells in them, For where two or three are gathered together in my name, there am I in the midst of them. — Catena Aurea by Aquinas
