Zwinger, Theodor a Swiss theologian, was born November 21, 1597, at Basle. He was a strict Calvinist, and defended the doctrine of predestination in a disputation it Heidelberg. In 1630 he was made antistes to the Church of Basle, to which position was attached a professorship of theology. The breaking of bread instead of the use of the host in the sacrament was introduced at Basle under his administration, respecting which event he published a report in his work on the Lord's Supper (1655). Of other works by his pen we mention a Commentary on Romans (1655). Both these works were published soon after his death, which occurred December 27, 1654. See Herzog, Real-Encyklop. s.v.
