God, in whose service alone is perfect freedom: We thank you for your prophets William Lloyd Garrison and Maria Stewart, who testified that we are made not by the color of our skin but by the principle formed in our soul. Fill us, like them, with the hope and determination to break every chain of enslavement, that bondage and ignorance may melt like wax before flames, and we may build that community of justice and love which is founded on Jesus Christ our cornerstone; who with you and the Holy Spirit lives and reigns, one God, now and for ever. Amen.
