Augustine of Hippo
Catena Aurea · Johannesevangelium 7
In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink. He that believeth on me, as the Scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
(Tract. xxxii. 2.) For there is an inner thirst, because there is an inner man: and the inner man of a certainty loves more than the outer. So then if we thirst, let us go not on our feet, but on our affections, not by change of place, but by love.
