Church Fathers on Luke 6:5

Not only in the form of expression but in His very practice and mode of action, did the Lord begin to absolve man from the observance of the old law. Hence it is said, And it came to pass that he went through the corn fields, &c.

For His disciples having no opportunity for eating because the multitudes thronged so, were naturally hungry, but by plucking the ears of corn they relieved their hunger, which is a mark of a strict habit of life, not seeking for prepared meats, but mere simple food.

Now He says, on the second sabbath after the first, because the Jews called every feast a sabbath. For sabbath means rest. Frequently therefore was there feasting at the preparation, and they called the preparation a sabbath because of the feast, and hence they gave to the principal sabbath the name of the second-first, as being the second in consequence of the festival of the day preceding.
