Pedro Ross was born in 1556 in Germany, son of a Lutheran pastor. He studied theology at the universities of Erfurt and Wittenberg, 1575-1579, and grew to become a pastor himself. It was a time of religious wars in Europe, and various times he had to flee or go into hiding and minister to his congregations secretly in home meetings. He was a theological writer, defending Lutheran theology chiefly from Calvinistic opponents. He also preached with great electrical power and usefulness. In 1588 he became pastor at Altwildungen, in 1596 he became pastor at Unna in Westphalia, and in 1601 pastor in Hamburg. But he is remembered currently for composing two hymns. Even though he was pastor in Westphalia, the plague took 1300 of his parishioners, primarily in the latter fifty percent of 1597, 170 in a single week. To convenience his parishioners, he wrote a series of meditations which he referred to as Freudenspiegel (Mirror of Joy), and to this he appended two hymns, both of which have turn out to be globe-renowned.
