Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
And seeing the multitudes, He went up into a mountain: and when He was set, His disciples came unto Him. And He opened His mouth, and taught them, saying, Blessed are the poor in spirit: for theirs is the kingdom of heaven.
(Id. de Serm. in Mont. i. 1.) Augmentation of ‘spirit’ generally implies insolence and pride. For in common speech the proud are said to have a great spirit, and rightly—for wind is a spirit, and who does not know that we say of proud men that they are ‘swollen,’ ‘puffed up.’ Here therefore by poor in spirit are rightly understood ‘lowly,’ ‘fearing God,’ not having a puffed up spirit.
