Hebrews 1:1
1God, having in the past spoken to the fathers through the prophets at many times and in various ways,
Wesley: at various times and degrees more explicit knowledge was given; in visions, dreams, and revelations of various kinds—opposed to the one entire and perfect revelation in Jesus Christ. The very number of the prophets showed that they prophesied only in part.
Classical Arminians share the high christology of the prologue: the God who spoke by the prophets now speaks by the Son. The diversity of former speech is not rival revelation; it prepares for the Son’s perfect word, which must still be heard and heeded.
Calvin: God formerly addressed the fathers by the prophets; he still sets before us but one God, that no one might think the Law militates against the Gospel. The variety of times and manners was an evidence of imperfection; God would have followed the same mode perpetually had the mode been perfect and complete.
One unchanging God speaks; the fragmentary prophetic word is true but incomplete. The King who governs has always spoken; the contrast is not rival deities but progressive disclosure culminating in the Son.
