On the Ancient Method of Infant Baptism in the English Church

The Second Council of Calcuith, England AD 816

Let Presbyters also know that when they administer Baptism they ought not to pour the consecrated water upon the infants’ heads, but let them always be immersed in the font; as the Son of God Himself afforded an example unto all believers when He was three times immersed in the river Jordan. (Canon 11)
