the transition here is faulty, one we dont know what infinity is and two we dont know fully the expression of his mercy
theres no superbrain i'm afraid only a recollection of grueling philosophy lessons in highschool but he did express himself in less technical fashion here:
"As to the question of what God, the exemplar of true life, really is, whether he is fire, or spirit, or light, or thought, or something else, this is irrelevant to faith. And so likewise is the question as to why he is the exemplar of true life, whether this is because he has a just and merciful disposition, or because all things exist and act through him and consequently we, too, understand through him, and through him we see what is true, just and good. On these questions it matters not what beliefs a man holds. Nor, again, does it matter for faith whether one believes that God is omnipresent in essence or in potency, whether he directs everything from free will or from the necessity of his nature, whether he lays down laws as a rule or teaches them as being eternal truths, whether man obeys God from free will or from the necessity of the divine decree, whether the rewarding of the good and the punishing of the wicked is natural or supernatural. The view one takes on these and similar questions has no bearing on faith, provided that such a belief does not lead to the assumption of greater license to sin, or hinders submission to God. Indeed … every person is in duty bound to adapt these religious dogmas to his own understanding and to interpret them for himself in whatever way makes him feel that he can the more readily accept them with full confidence and conviction."
for more reading this is not bad, though i didnt read it all
