Origen

“ May it be that as bread nourishes and makes strong, and is said to strengthen the heart of man, but wine, on the contrary, pleases and rejoices and melts him, so ethical studies, bringing life to him who learns them and reduces them to practice, are the bread of life, but cannot properly be called the fruit of the vine, while secret and mystical speculations, rejoicing the heart and causing those to feel inspired who take them in, delighting in the Lord, and who desire not only to be nourished but to be made happy, are called the juice of the true vine, because they flow from it. ”
