Tertullian

“ Oh, miserable incredulity, which quite deniest to God His own properties, simplicity and power! What then? Is it not wonderful, too, that death should be washed away by bathing? But it is the more to be believed if the wonderfulness be the reason why it is not believed. For what does it behove divine works to be in their quality, except that they be above all wonder? [2] We also ourselves wonder, but it is because we believe. Incredulity, on the other hand, wonders, but does not believe: for the simple acts it wonders at, as if they were vain ”

“ For if God is wise and powerful (which even they who pass Him by do not deny) , it is with good reason that He lays the material causes of His own operation in the contraries of wisdom and of power, that is, in foolishness and impossibility; since every virtue receives its cause from those things by which it is called forth. ”

“ There is absolutely nothing which makes men’s minds more obdurate than the simplicity of the divine works which are visible in the act, when compared with the grandeur which is promised thereto in the effect ”
