Ambrose of Milan
Catena Aurea · Lukasevangelium 20
Then began he to speak to the people this parable; A certain man planted a vineyard, and let it forth to husbandmen, and went into a far country for a long time. And at the season he sent a servant to the husbandmen, that they should give him of the fruit of the vineyard: but the husbandmen beat him, and sent him away empty. And again he sent another servant: and they beat him also, and entreated him shamefully, and sent him away empty. And again he sent a third: and they wounded him also, and cast him out. Then said the lord of the vineyard, What shall I do? I will send my beloved son: it may be they will reverence him when they see him. But when the husbandmen saw him, they reasoned among themselves, saying, This is the heir: come, let us kill him, that the inheritance may be our’s. So they cast him out of the vineyard, and killed him. What therefore shall the lord of the vineyard do unto them? He shall come and destroy these husbandmen, and shall give the vineyard to others. And when they heard it, they said, God forbid. And he beheld them, and said, What is this then that is written, The stone which the builders rejected, the same is become the head of the corner? Whosoever shall fall upon that stone shall be broken; but on whomsoever it shall fall, it will grind him to powder.
The vineyard is also our type. For the husbandman is the Almighty Father, the vine is Christ, but we are the branches. (John 15:5.) Rightly are the people of Christ called a vine, either because it carries on its front the sign of the cross, or because its fruits are gathered in the latter time of the year, or because to all men, as to the equal rows of vines, poor as well as rich, servants as well as masters, there is an equal allotment in the Church without distinction of persons. And as the vine is married to the trees, so is the body to the soul. Loving this vineyard, the husbandman is wont to dig it and prune it, lest it grow too luxuriant in the shade of its foliage, and check by unfruitful boastfulness of words the ripening of its natural character. Here must be the vintage of the whole world, for here is the vineyard of the whole world.
