Final answer:
The recurring distinction between liberal and conservative scholars in New Testament theology is the issue of the federal government's involvement in social and religious matters.
Step-by-step explanation:
The recurring distinction between liberal and conservative scholars in New Testament theology, as noted by Enns, is the issue of the federal government's involvement in social and religious matters. Conservative scholars tend to be critical of the government's legalization of abortion, the doctrine of separation of church and state in public schools, and the growing toleration of homosexuality. On the other hand, liberal scholars may support these government actions and argue for a more inclusive and progressive approach.
