Augustine of Hippo

Honor the holy church as your mother. Love her, proclaim her the Jerusalem which is above, the holy city of God. She it is who, in this faith which you have heard, bears fruit and grows in the whole world, the church of the living God, the pillar and buttress of the truth. She tolerates the wicked in the communion of the sacraments, knowing that they are due to be separated from her at the end and withdrawing from them meanwhile in the dissimilarity of their morals.
