"Sacraments do not simply bless things as they are, but transform them in a dynamic manner towards what they should be. In the case of the Eucharist, this transformation is complete. But in those sacraments that involve the freedom of persons, the transformation can only be seen as a dynamic. Man and woman are blessed towards what they should be. The heart of marriage is self-emptying love towards the purpose of union and the procreation of children. It does not exist for the self-fulfillment of our tragic existence ... but towards an end that is only just now being made present." - Fr. Stephen

"In the ancient Church, crowns are a symbol of martyrdom. The word "martyr" means witness. The common life of the bride and groom is to bear witness to the Presence of Christ in their lives and in the world. Martyrdom is usually associated with death. So the reality of God's Kingdom in the life of the husband and wife will necessarily take the form of dying to one's self, to one's will, and the giving of one's life totally to the other, and through the other, to Christ." - Wikipedia

"Bless (+) this marriage and grant unto these Your servants a peaceful life, length of days, chastity, love for one another in a bond of peace, offspring long‑lived, fair fame by reason of their children, and a crown of glory that does not fade away." - from the crowning service
