Because it is the nature of love to create, a marriage itself is something which has to be created, so that, together we become a new creature.

To marry is the biggest risk in human relations that a person can take…If we commit ourselves to one person for life this is not, as many people think, a rejection of freedom; rather it demands the courage to move into all the risks of freedom, and the risk of love which is permanent; into that love which is not possession, but participation…It takes a lifetime to learn another person…When love is not possession, but participation, then it is part of that co-creation which is our human calling, and which implies such risk that it is often rejected.
