Ebola and COVID-19, two devastating infectious diseases that spread rapidly through populations, crossing boundaries of all sorts, put local, national, and international health systems to crucial tests. They also try religious communities, locally and globally. The authors of this guest post, Katherine Marshall, Olivia Wilkinson and Dave Robinson, argue that we are learning vital lessons from both experiences. First, religion and science must combine their strengths. For this, religious voices must be at the medical and public health crisis tables, and scientific voices at the religious ones. Second, both the distinctive strengths and potential limitations of each need to be understood and appreciated in planning and operationalizing responses at all levels, from global to local.
