Bernard of Clairvaux on the Doctrine of the Trinity

It is rashness to search too far into it. It is piety to believe it. It is life eternal to know it. And we can never have a full comprehension of it, till we come to enjoy it.

—Bernard of Clairvaux, as quoted by Fred Sanders, "3 Pithy Remarks on Handling the Doctrine of the Trinity" at ScriptoriumDaily.
