Augustine on patience
Augustine of Hippo’s On Patience. . . confines itself to two questions: where does Christian patience come from and what is its character? . . . Augustine argues that patience has but a single source, the free and unmerited grace of God, and defines patience as that which helps us “endure evils with equanimity so as not to abandon, through a lack of equanimity, the good through which we arrive at the better.”
