All Christians agree that Jesus fulfills the expectations of Psalm 2, but it’s debated if this reign has already begun or whether it entirely awaits His return. Much hinges on how one interprets NT quotations and allusions to Psalm 2 (e.g. Mk 1:11; Acts 13:33), although this does not exhaust the discussion. Other related texts and concepts help shed light on the question. One concept is that of Zion.
