So I’ve got to prove to you that God too does “worship” human beings, or you will consider, perhaps, that I have used the word very carelessly, and begin arguing against me in your thoughts, and finding fault with me because you don’t in fact grasp what I’ve been saying.
Augustine, Sermon 87 – Preached on a Sunday at the time of the vintage on what is written in the gospel of Matthew 20:1-16: *The kingdom of heaven is like a man, a householder, who sent workmen into his vineyard. *
