In 2020, the religious factor turned out to gain importance to both protest mobilizations and to government repression in Belarus, where the initiatives of religious groups had fostered collective action in the state system that was punitive against any dissent. This happened for the first time in the country, which had been affected by the legacies of Soviet anti-religious policies. The forms of protest that churches could suggest fitted neatly into the non-democratic settings of Belarus, providing a necessary opportunity structure for otherwise forbidden mobilizations. Analyzing the attitudes of the Orthodox, Catholic, and Protestant Churches toward the events of 2020 in Belarus, this research note discusses why their social contract with the authoritarian regime was broken. We argue that the churches' stance and the role they played at a time of political turmoil confirmed their status as influential non-state actors who are capable of having their say in the rough circumstances of an authoritarian and repressive political regime. At the same time, it has also confirmed the limits of the authoritarian state to influence religious institutions and the growing opportunities for clergy and laypeople from these institutions to have a common say on important issues of moral and ethical dimensions, inspired by Christian principles and values.
