We continue this Sunday exploring our Christian faith through the hymns we sing. After joining with the Church in Jerusalem of the first three centuries (Let all mortal flesh keep silence ... for Christ our God to earth descendeth), and with those around John of Damascus in the 8th century (The day of resurrection, earth tell it out abroad), and with Francis of Assisi in the 12th century (All creatures of our God and King, lift up your voices and with us sing), we arrive at 17th century England ... and what a story lies behind this hymn! It is one of Christian witness embodied in the life of its author, and of challenge in its words to us today.
