We do not think that detachment from creatures is the same for all, whether for the greatest saints or for those souls that have reached a minimal perfection. And the principal reason is, that perfection excludes not only faults that are directly voluntary, but also those that are indirectly voluntary; those which proceed from negligence and a relative tepidity, from a secret and semi-conscious egoism that does not allow the depth of the soul to belong completely to God. Likewise there is a certain co-relation between the intensive growth of charity and its extension, in consequence of which charity gradually excludes even those obstacles which we more or less unconsciously oppose to the work of grace in our souls. –Father Reginald Garrigou-Lagrange, O.P.
