John Chrysostom, Homilies on Repentance and Almsgiving 3.4.19:
Have you sinned? Enter into the church and wipe away your sin. The number of times you fall down in the marketplace equals the number of times you rise up. Likewise, as many times as you sin, repent for your sin: do not become discouraged. And if you sin a second time, repent a second time....And if you are in the depths of old age and you sin, enter into the church and repent, because the church is a hospital, not a court of justice.
Richard Sibbes, The Bruised Reed and Smoking Flax, in Works, Vol. 1, p. 57:
The church of Christ is a common hospital, wherein all are in some measure sick of some spiritual disease or other; that we should all have ground of exercising mutually the spirit of wisdom and meekness.
Simon Patrick, The Heart's Ease; or, A Remedy Against Trouble, in Works, Vol. 3, pp. 504-505:
...over the Gospel we may write what the Egyptians did over their library, ..., 'this is the hospital for sick souls.'
