“When you give, give generously, with a joyous countenance, and give more than you are asked for…Do not separate the rich from the poor or try to discriminate the worthy from the unworthy, but let all persons be equal in your eyes for a good deed.”
Isaac of Nineveh (c. 700), Bishop of Nineveh and Monk, Ascetical Homilies 4. (ACCS.IX.PESOS-274).
