The full text of his address to Congress is here.
It is a rich and thoughtful speech, highlighting the necessity for dialogue—a word he used often—and a hunger for the common good.
The conclusion:
Three sons and a daughter of this land, four individuals and four dreams: Lincoln, liberty; Martin Luther King, liberty in plurality and non-exclusion; Dorothy Day, social justice and the rights of persons; and Thomas Merton, the capacity for dialogue and openness to God. Four representatives of the American people.
…A nation can be considered great when it defends liberty as Lincoln did, when it fosters a culture which enables people to “dream” of full rights for all their brothers and sisters, as Martin Luther King sought to do; when it strives for justice and the cause of the oppressed, as Dorothy Day did by her tireless work, the fruit of a faith which becomes dialogue and sows peace in the contemplative style of Thomas Merton. In these remarks I have sought to present some of the richness of your cultural heritage, of the spirit of the American people. It is my desire that this spirit continue to develop and grow, so that as many young people as possible can inherit and dwell in a land which has inspired so many people to dream. God bless America!
