I’m currently in a Church History class going through the Reformation period of Christianity. During the Reformation, Martin Luther’s partner in crime (literally) was Philipp Melanchthon. After Luther’s death, Melanchthon carried the torch as a leader of the movement spreading throughout the Medieval world. In the years following the start of the Reformation, there were several different strains of non-Catholic Christianity that popped up.
To withstand the Catholic majorities at the time, these non-Catholic groups started talking about what it would look like to unify under one banner. Believe it or not, even though all these movements were really young and were reacting to the same problems they saw in Catholicism, these groups had really big differences between them that were hard to overcome.
In these conversations, an aging Melanchthon used an old Greek philosophical phrase to suggest a way forward: Adiaphora. Greek for “indifferent things”, he used it to describe how he felt that some beliefs and practices could be considered adiaphora (non-essentials), and could be compromised on for the same of unity. He argued with his fellow Lutherans that some beliefs were more essential to Christianity than others and didn’t require so much division. The others around him, of course, disagreed.
This got me thinking about the trajectory this set for us today. We now feel perfectly free to think a whole host of different things and still call others Christians. And yet still, much of Christianity’s most bitter judgmentalism and cries of heresy, unfaithfulness, sin, and arrogance are directed towards other who are also trying to follow the God of Jesus best they can. This has caused rifts, schisms, splits, and divisions into a huge number of Church denominations. Is this healthy for us? What does Christian “unity” look like? Do we all need to look the same?
