||Oh Happy Day is a hymn written in the mid-18th century ("Oh happy day that fixed my choice") by English clergyman Phillip Doddridge (based on Acts 8:35) set to an earlier melody (1704) by J. A. Freylinghausen. By the mid-19th century it had been given a new melody by Edward F. Rimbault and was commonly used for baptismal or confirmation ceremonies in the UK and USA. The power to wash sins away. What an awesome concept.
