Brothers and sisters,
I could not talk to you as spiritual people,
but as fleshly people, as infants in Christ.
I fed you milk, not solid food,
because you were unable to take it.
Indeed, you are still not able, even now,
for you are still of the flesh.
While there is jealousy and rivalry among you,
are you not of the flesh, and walking
according to the manner of man?

Epistle of Paul: First Corinthians

And hence arises the love of its neighbours, for it esteems them, and judges them not as it was wont to do aforetime, when it saw that itself had great fervour and others not so. It is aware only of its own wretchedness, which it keeps before its eyes to such an extent that it never forgets it, nor takes occasion to set its eyes on anyone else. This was described wonderfully by David, when he was in this night, in these words: ‘I was dumb and was humbled and kept silence from good things and my sorrow was renewed.’ This he says because it seemed to him that the good that was in his soul had so completely departed that not only did he neither speak nor find any language concerning it, but with respect to the good of others he was likewise dumb because of his grief at the knowledge of his misery. –St John of the Cross ‘Dark Night of the Soul’.
