The following is a reflection on Isaiah 8:1-8, the Old Testament lesson properly appointed for Trinity Sunday, Year B, according to the Revised Common Lectionary. The vision of Isaiah has always captivated me. It informs my vision of God’s Heavenly Kingdom perhaps more than anything else. It’s grand. Regal. Sweeping.
This isn't a text to absolutize. You can't (or at least shouldn't) attempt to build a theology of the trinity around this...This is Paul invoking the fullness of God in prayer over a community (koinonia) in Corinth that had it's issues.
