Perhaps the reason why the standard of holiness among us is so low, why our attainments are so poor, our view of the truth so dim, our belief so unreal, our general notions so artificial and external is this, that we dare not trust each other with the secret of our hearts. We have each the same secret, and we keep it to ourselves, and we fear that, as a cause of estrangement, which really would be a bond of union. We do not probe the wounds of our nature thoroughly; we do not lay the foundation of our religious profession in the ground of our inner man; we make clean the outside of things; we are amiable and friendly to each other in words and deeds, but our love is not enlarged, our bowels of affection are straitened, and we fear to let the intercourse begin at the root; and, in consequence, our religion, viewed as a social system, is hollow. The presence of Christ is not in it.
--Blessed John Henry Newman, “Christian Sympathy”, Parochial and Plains Sermons, Vol.5
