Tertullian

“ For so entirely one and the same was the nature of the Divine Beings, the good and the severe, as shown both by the same examples and in similar proofs, that It willed to display Its goodness to those on whom It had first inflicted Its severity. The difference in time was no matter of surprise, when the same God was afterwards merciful in presence of evils which had been subdued, [6] who had once been so austere whilst they were as yet unsubdued. Thus, by help of the Antitheses, the dispensation of the Creator can be more readily shown to have been reformed by Christ, rather than destroyed ”

“ The truth is, [3] they [4] rather unite the two Beings whom they arrange in those diversities (of attribute) , which yet are compatible in God. For only take away the title of Marcion’s book, [5] and the intention and purpose of the work itself, and you could get no better demonstration that the self-same God was both very good and a Judge, inasmuch as these two characters are only competently found in God. Indeed, the very effort which is made in the selected examples to oppose Christ to the Creator, conduces all the more to their union. ”
