 Trubetskoy believed that the personality of Jesus Christ, which united the human and divine wills, is crucial for understanding of all aspects and dimensions of Christianity.He viewed Christian teaching not solely as a set of ethical norms but as a system of truth which can be perceived and understood exclusively through special revelation (see fideism).His viewpoint differed both from the official doctrine of the Orthodox Church and from the beliefs of liberal intellectuals, who reduced the Christian faith to an egalitarian ethic.
