One of the major premises of Kierkegaardian Christian existentialism entails calling the masses back to a more genuine form of Christianity. This form is often identified with some notion of Early Christianity, which mostly existed during the first three centuries after Christ's crucifixion. Beginning with the Edict of Milan, which was issued by Roman Emperor Constantine I in AD 313, Christianity enjoyed a level of popularity among Romans and later among other Europeans. And yet Kierkegaard asserted that by the 19th century, the ultimate meaning of New Testament Christianity (love, cf. agape, mercy and loving-kindness) had become perverted, and Christianity had deviated considerably from its original threefold message of grace, humility, and love.
