For if that which is done away was glorious, much more that which remaineth is glorious.
Was glorious - literally, 'was with glory;' or 'marked by glory' х dia (G1223) doxees (G1391)].
That which remaineth - "the everlasting gospel" (Revelation 14:6). Not 'the ministry,' but the Spirit, and His accompaniments, life and righteousness.
Is glorious - literally, 'is in glory.' The х dia (G1223)] 'with' or 'by' is appropriate to that of which the glory was transient. 'In' to that of which the glory is permanent. The transient covenant of condemnation had a transient glory: the abiding covenant of justification has an abiding glory. The contrast (2 Corinthians 3:10-11) proves that Paul's chief opponents at Corinth were Judaizers.
