Though appealing to the generation of 'emerging adults' (age 18-25), MTD results in undesirable life-outcomes that prompt religious scholars, theologians, and sociologists to carefully study its roots, expressions, and possible alternatives.
Using S.Kierkegaard's religious existentialismas a case study, the authors argue that religious existentialism has the potential to face the detrimental effects ofMTD and to reinvigorate stagnating religious communities.
