Every icon likeness of God is forbidden by Deut 4:12ff worshipped or not:
15 And take good heed to your hearts,
for ye saw no likeness
ὅτι οὐκ εἴδετε ὁμοίωμα
in the day in which the Lord spoke to you in Choreb in the mountain out of the midst of the fire:
16 lest ye transgress, and make to yourselves
a carved likeness,
γλυπτὸν ὁμοίωμα
every icon likeness,
πᾶσαν εἰκόνα ὁμοίωμα
the likeness of male or female, (Deu 4:15-16 Septuagint)
