Tertullian

“ Who wishes for what he desires not? Moreover, care will be another companion of the will. For who will wish for any object and desire to have it, without also caring to obtain it? When, therefore, (Marcion’s god) felt both a will and a desire for man’s salvation, he certainly occasioned some concern and trouble both to himself and others. ”

“ Again, [13] nothing will ever run its course without hostile rivalry, [14] which shall not (itself) be without a hostile aspect. In fact, [15] when willing, desiring, and caring to deliver man, (Marcion’s god) already in the very act encounters a rival, both in Him from whom He effects the deliverance (for of course [16] he means the liberation to be an opposition to Him) , and also in those things from which the deliverance is wrought (the intended liberation being to the advantage of some other things) . ”

“ Now, since all these emotions are present to rivalry; since, moreover, the rivalry which arises in liberating man excites them; and since, again, this deliverance of man is an operation of goodness, it follows that this goodness avails nothing without its endowments, [18] that is to say, without those sensations and affections whereby it carries out its purpose [19] against the Creator; so that it cannot even in this be ruled [20] to be irrational, as if it were wanting in proper sensations and affections. ”
