I'm listening to Cooper's critique of the Reformed position of the second commandment. He's worth listening to but does make mistakes. For example, he claims he had never heard of images being commanded by God under the old carnal covenant and used the commandment to use images to adorn the old Temple as a positive command to use crucifixes and images of Jesus. The problem is, he failed to understand the Reformed position which is, true worship is instituted, commanded by God and limited to divine revelation.
"The light of nature shows that there is a God, who has lordship and sovereignty over all, is good, and does good unto all, and is therefore to be feared, loved, praised, called upon, trusted in, and served, with all the heart, and with all the soul, and with all the might. But the acceptable way of worshipping the true God is instituted by Himself, and so limited by His own revealed will, that He may not be worshipped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representation, or any other way not prescribed in the holy Scripture." Westminster
Since we are not commanded to make crucifixes and images of Christ for use during worship we shouldn't. The command to adorn the Ark of the Covenant with Angels was just that, a command given to God's people at a certain time, to do something specific. The second commandment reads, "Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am o jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of then that hate me; and shewing mercy unto thousands of them that love me and keep my commandments." Exod 20: 4-6.
"YOU" are not to create images for worship, out of your own imagination. Since Angels were commanded by God to be used...well, they were used. Even under the old covenant Saints would never have created images for worship unless commanded or they had fallen away.
Yours in the Lord,
