I quote this, as sent to me by a friend; but the only passage at all
approaching to it which I can verify is the following:

"Quidquid in Scripturis valet, quidquid in eis spiritualiter sentit,
maxime in silvis et in agris           et orando se confitetur
accepisse, et in hoc nullos aliquando se magistros habuisse nisi
quercus et fagos joco illo suo gratioso inter amicos dicere solet.
