J. G. H. Barry, Our Lady Saint Mary
“ In other words, we understand the mind of God and attain to the illumination of the conscience, through sympathetic response to the will so far as we have seen it. And each new response, in its turn, carries us to a deeper and clearer understanding of the will. That is to say, our conscience, by habitual response to God's will, so far as it knows it, is so illumined as to be able to make trustworthy judgments on new material submitted to it. ”
