This paper explores the problem of religious phenomenological approaches to COVID-19 in the first half and Christian social ethics in the second half. The reli- gious phenomenological approach is based on a survey of Korean Protestants’ perceptions during the COVID-19 era. Looking at how Protestant faith patterns changed in the wake of COVID-19, I summarized the characteristics of religious phenomenology after COVID-19 as 1) the arrival of non-religious societies, 2) the destruction of religious aura, and 3) the reconstruction of worship. The suspen- sion and disruption of worship due to COVID-19 is read as an incident that Korean society has entered the threshold of non-religious society. Bonhoeffer’s “Before God, with God, without God” statement is expected to be an important clue to interpreting non-religious society after COVID-19. The increase in non-face-to-face online worship triggered by COVID-19 has collapsed the aura of existing worship, and existing one-way worship services are being asked to com- municate with each other and to change the form of worship. After the religious phenomenological analysis, I will propose three alternatives to the COVID-19 era: (1) Christian social ethics suitable for the secular age, (2) Christian social ethics overcoming anti-intellectualism, and (3) the ethics of hospitality toward others.
