FAKKIR.XYZ | JURNAL – This thesis will examine past research to study the postmodern era’s core idea and shed light on how this idea relates to modernism, i.e., the previous era. The thesis will also consider the foundation upon which these eras are built and see what they have in common and what sets them apart. The eras have humanism in common, but conformism (or standardization) and pluralism separate them. Through the dualism of Greek philosophy and the fall story of the Old Testament, I will show the origins of conformism and pluralism and propose a path to overcome them. I will discuss how, as Christianity comes across Greek dualism, the field of practical theology and theological practice has trended toward prioritizing theoria over praxis. In the tradition of Hebrew beliefs and the good news of Jesus Christ, practice and life are one, and I will emphasize that if one was to be prioritized, it should be practice. Life in the early Churches, which began through Jesus Christ and his disciples, was based on the practice of the Triune God’s love through the crucifixion of Jesus Christ. Hence, a newly reflected paradigm based on the threefold love of Trinity is required in the postmodern era.
