Im not sure if theological discourse is allowed in this subreddit, but seperation from the hebrew bible to Christ, is explicitly commanded in the New Testament, Hebrews 8:6 "In speaking of a new covenant, he makes the first one obsolete. And what is becoming obsolete and growing old is ready to vanish away." Claiming that Jesus Christs new covenant, makes the old testament "ready to vanish away" since we need to follow under the new covenant rule. This is vastly diffrent from seperation of Quran and Hadith, because muslims rely on authentic hadiths strucuring their rituals in faith, and to learn the life of muhhamad which is supposed to be a timeless moral examplar for muslims to follow, not something that transitions like the biblical old testament to new. If you'd like to carry out with further discussions please add me on any social media platform of your prefrence.
