Aristophanes [writes]: "For [the] opportune time, which for men is the greatest chairman of every deed ..." He means that the opportune time is the timely and most/very useful [thing] for each activity: where even serious [efforts] occurring at the wrong time are not accepted, as a physician conversing with one who suffers about the nature of his illness; as if one were to converse with drunken men about temperance.[1] For what is good, if it does not occur in a good manner, [is] not good.[2]
And elsewhere: "Justinian, whether not thinking opportunely because of old age, or for some other reason, would have jumbled the orthodox belief concerning Christ, if he had not departed from among men."[3]
