And let us not waver or move away from the Church when we see imperfections in some of her members, because, individually, we are all weak and sinful. But the Church does not cease to be holy for all that; holy in her laws and in the doctrine entrusted to her by God, holy in her Head, Jesus Christ, her divine founder and Saviour, holy in the divine Spirit which animates and helps her, and

in the life of grace generated and nourished by the Sacraments.
