Aaron’s feast: Cras solemnitas Jehovae—honor of the cast image referred to the true patriarchal God
Aaron’s proclamation names Jehovah’s feast, not a rival god’s.
So the calf-honor was explicitly referred to the patriarchal true God.
Latin
XXIX. Similiter quum Aaron, in honorem vituli a se fusi, festum indixit, praeconis voce clamavit, Cras solemnitas Domini est. Ubi textus Hebraeus habet, Cras solemnitas est Jehovae, quod nomen proprium est veri illius Dei, quem Patriarchae coluerunt. Argumento manifesto, Israelitas ad verum Patrum suorum Deum retulisse honorem illum, quem imagini a se conflatae exhibebant.
