He was the Word, that spake it:

He took the bread and brake it;

And what that Word did make it,

I do believe and take it.

John Donne. 1573-1631. Divine Poems. On the Sacrament

There is more in sacramental bread than in common bread. Though the nature is not
changed, the use is changed. It does not only nourish the body as it did before, but also
it brings a bread with which it nourishes the soul. For as sure as we receive bread, so
sure we receive Christ – not only the benefits of Christ, but Christ. — Henry Smith
