"The implicit connotation of the Son as the type and die used to imprint the image of God on the coins of humanity - the Son who became incarnate as the chief coin of the Father - emerges in these various instances of material connection between coinage and Christ. Actual coins carry on the work of incarnation as material symbols making theological claims: they proclaim Justinian's imperial submission to Christ, they distinguish the hypostatic union from the body of the virgin mother, and they serve as ritual objects of iconophilic practice. Significantly, this conceptual connection between Christ and coins emerges in political contexts during declarations of, or struggles for, sovereignty. The implicit idea of Christ as principal coin of the Father's kingdom proves itself repeatedly useful in imperial attempts at consolidation of power."
