Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 10:29-37

“But He says, passed by, (Rom. 3:20; 8:3.) because the Law came and stood till its time foreordained, then, not being able to cure, departed. Mark also that the Law was not given with this previous intention that it should cure man, for man could not from the beginning receive the mystery of Christ. And therefore it is said, And by chance there came a certain priest, which expression we use with respect to those things which happen without forethought.”
