VDMA, standing for the Latin motto Verbum Domini Manet in Aeternum. This symbol was inscribed on swords, cannons and armor used by the Smalcaldic League which was formed to be a mutual defense organization, against the Catholic princes trying to overthrow the Reformation in the various territories of Germany that had embraced it.
The Word of the Lord Endures Forever is the motto of the Lutheran Reformation, a confident expression of the enduring power and authority of God’s Word. The motto is based on Isaiah 40:6-8 quoted by 1 Peter 1:24-25. It first appeared in the court of Frederick the Wise in 1522. He had it sewn onto the right sleeve of the court’s official clothing, which was worn by prince and servant alike. It was used by Frederick’s successors, his brother John the Steadfast, and his nephew John Frederick the Magnanimous. It became the official motto of the Smalcaldic League and was used on flags, banners, swords, and uniforms as a symbol of the unity of the Lutheran laity who struggled to defend their beliefs, communities, families and lives against those who were intent on destroying them.*
