In the most recent issue of Emmanuel Magazine, the "editorial" includes a quote from Cardinal Newman:

So again, they who enter Holy Orders promise they know not what, engage themselves they know not how deeply, debar themselves of the world's ways they know not how intimately, find perchance they must cut off from them the right hand, sacrifice the desire of their eyes and the stirrings of their hearts at the foot of the Cross, while they thought, in their simplicity, they were but choosing the quiet easy life of "plain men dwelling in tents."

The editor, Paul Bernier, SSS, admits he does not have the quote's original provenance. Can any Newmanians be of assistance in that regard?
