Wedding readings

Research has commenced on what to read at the wedding. I found a few excerpts on an About.com site -- now I have to read the original works.

We both like this bit from "The Irrational Season" by Madeleine L'Engle.
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.

I feel obliged to somehow incorporate Sappho. This fragment for example.
Love holds me captive again
and I tremble with bittersweet longing

When our high priestess, MaryJoan, convenes the ceremony and defines our commitment, I'm thinking something from the Massachusetts Supreme Court Chief Justice Margaret H. Marshall would be good.
Civil marriage is at once a deeply personal commitment to another human being and a highly public celebration of the ideals of mutuality, companionship, intimacy, fidelity and family. ... Because it fulfills yearnings for security, safe haven and connection that express our common humanity, civil marriage is an esteemed institution and the decision whether and whom to marry is among life's momentous acts of self-definition.
