Those, therefore, who do not partake of Him, are neither nourished into life from the mother’s breasts, nor do they enjoy that most limpid fountain which issues from the body of Christ; but they dig for themselves broken cisterns out of earthly trenches, and drink putrid water out of the mire, fleeing from the faith of the Church lest they be convicted; and rejecting the Spirit, that they may not be instructed.

-Irenaeus of Lyons (d. ca. 202)
