Right, and no-one (Jewish or Christian) is authorized in any passage of Scripture to make an Icon of the Father or of the Holy Spirit (well, in the case of the Holy Spirit, Christendom has generally permitted that His activity may be abstractly represented with the image of a Dove -- an Iconic representation which is often found in Protestant imagery).
But that doesn't change the fact that the Jews were directed to make Icons of the Heavenly Cherubim, which we must therefore conclude did not violate the Second Commandment (Second Commandment, OP... SECOND Commandment!)
Nor does it change the fact that Jesus Himself is, according to Hebrews 1, the "Express Image" of the Invisible Father.
More importantly, the making of the Cherubim does not change God's original desire for us not to make images that represent God.
