Dr. Martin Luther's seal expresses his theology and his faith. He designed it himself.

• In the centre is a black cross indicative of Christ's dreadful sacrifice on the cross for every sinner who ever lived.
• The cross is in the centre of a red heart, to show that faith causes love, joy and peace to grow in the human heart.
• The the red heart is on a white rose (Luther's favourite flower) because white is the colour of angels and blessed spirits.
• The white rose is against a blue-sky background to symbolize the Christian's hope for the coming joys of heaven.
• The seal is enclosed in a gold ring, showing that the bliss of heaven is unending.
