“My duty towards God, is to believe in him, to fear him, and to love him… to worship him, to give him thanks, to put my whole trust in him, to call upon him, to honour his holy Name and his Word, and to serve him truly all the days of my life.”

From the Catechism in Cranmer’s first prayer book (1549).
