Luke 6:20

St. Matthew (v. 3. 10.) mentions eight beatitudes, St. Luke only four; but St. Luke only gives an abridgment in this place of the discourse, which St. Matthew gives more at length. We are also to remark, that in these four the whole eight are comprised, and that both evangelists place poverty in the first place, because it is the first in rank, and, as it were, the parent of the other virtues; for he who hath forsaken earthly possessions, deserves heavenly ones. Neither can any man reasonably expect eternal life, who is not willing to forsake all in affection, and in effect also, if called upon for the love of Jesus Christ. (St. Ambrose) --- Not that every one under great poverty is happy, but that the man who prefers the poverty of Christ to the riches of the world, ought certainly to be esteemed such. Many indeed are poor in worldly substance, but are avaricious in affection; to such as these poverty is no advantage. Nothing that is against the will, merits reward; therefore all virtue is known by the will. Blessed, therefore, are the poor, who bear poverty for the sake of Christ: he himself hath already trodden the path before us, and taught us by his example that it leads to honour and enjoyment. (St. Cyril in St. Thomas Aquinas)
