Craig Blomberg lists four kinds of errors that the New Testament most strongly opposes: (1) any denial of the full humanity and deity of Christ; (2) any denial of salvation by grace through faith (either through some form of legalism, nomism, or ethnocentrism or through antinomianism); (3) the denial of the future bodily return of Christ; and (4) various distortions of the doctrine of sanctification, such as defeatism or triumphalism.
