Historian Tom Devine and former Herald editor Harry Reid say that much more should be done to mark and acknowledge the 450th anniversary of the Reformation of 1560.

The Catholic bishop of Osnabrück in northern Germany says the 16th-century Protestant Reformer Martin Luther offers a "positive challenge" to Protestant and Catholic churches.

16th-century reformer Jean Calvin can inspire a "reformation of values" in the face of the world's economic and ecological crises, a Swiss politician has said in marking the 500th anniversary of the Protestant leader's birth.

An international expert on church unity has urged the Roman Catholic Church to declare officially that its longstanding excommunication of Martin Luther no longer applies.
