Eddie Harper, the administrator of Sovereign Grace Puritan Group on Facebook shared:

“As a young Catholic priest Zwingli began to study the Bible. He taught himself Hebrew and Greek and memorised Paul’s epistles in the Greek New Testament. Zwingli was shocked to find that there was a world of difference between the teaching of the Bible and the teaching and practice of the Roman Catholic church.
In 1519 Zwingli began to systematically preach through the New Testament – beginning with the Gospel of Matthew. He opposed indulgences and preached the Gospel. He also secretly married!
Zwingli laid the foundations for the Reformation in Switzerland. In 1523 the City Council of Zurich voted to become Protestant by supporting Zwingli’s reforms. He died fighting to defend Zurich from attack in the battle of Kappel in 1531.
His last words were: “They can kill the body – but not the soul!”
