Read it again:
Exo 32:5 Now when Aaron saw this, he built an altar before it; and Aaron made a proclamation and said, "Tomorrow shall be a feast to the LORD."
"LORD" is:
yehovah
yeh-ho-vaw'
From H1961; (the) self Existent or eternal; Jehovah, Jewish national name of God: - Jehovah, the Lord. Compare H3050, H3069.
This word is ALWAYS used in scripture to designate the one, true God. It IS the name (or as close as we can come to the name) of the one, true God.
Aaron desired to honor the one true God. He created a golden calf to represent the one, true God. He proclaimed a feast to the one true God. God wasn't happy BECAUSE he had just spoken a commandment that we were to not make an image, any image, to represent him. He had already created the Passover and the days of unleavenend bread, biblical feasts of God.
The exact same situation occurs with Easter, only worse. Easter is closely associated with all sorts of pagan, idolatrous symbols. Easter is merchandised, packaged and sold. AND man has proclaimed that this is to honor the one, true God.
You're engaging in some serious eisegesis.
