You saw no form: can God ever be pictured?
God's divine nature remains invisible; the Son's actual human appearance is a different question.
Key points
- Deuteronomy 4 grounds the prohibition of images in God's invisibility. That principle seems to remain true after Christ.
- Deuteronomy warns against inventing a visible likeness for the God whose form Israel did not see at Horeb.
- Christian confession adds that the Word truly became flesh and was seen. An icon of Christ refers to the incarnate Son through his visible humanity.
- This does not turn the divine essence into a shape or give us a literal portrait of the Father.
- The opponent may grant that Jesus could have been seen while disputing devotional use of a later painting. Depictability and veneration need separate arguments.
