Faith is Not the Righteousness, Turretin
Turretin on faith and justification. (p75, Justification, ed Dennison, P and R, 1994)
First,the false mode of justification by faith (introduced by the Socinians and Romanists) must be removed. The act of believing is not considered as our righteousness with God by a gracious acceptation. A. Because receiving righteousness cannot be our righteousness itself formally. Rom 5:17-18)
B. Because faith is distinguished from the righteousness itself imputed to us, both because it is said to be “of faith” and “by faith” (Rom 1:17; 3:22; Phil 3:9) and because Christ with his obedience and satisfaction is that righteousness which is imputed to us (Is 53:11; Jer 23:6; I Cor 1:30; II Cor 5;21; Gal 3:13-14). Faith has this righteousness as its object, but with which it cannot be identified.
C. Because we are not justified except by a perfect righteousness. For we have to deal with the strict justice of God, which cannot be deceived. Now no faith here is perfect. Nor can it be considered as such by God and a gratuitous lowering of the law’s demands. For in the court of divine justice, there cannot be a room for a gracious acceptation which is an imaginary payment.
D. If faith is counted for righteousness, we will be justified by works because this faith cannot but have the relation of a work that justifies. And yet it is clear that in this business Paul always opposes faith to works as incompatible and two antagonistic means by which man is justified either by his own obedience or by another’s obedience.
“The faith of Abraham,” it is said, “was imputed to him for righteousness” (Gen 15:6; Rom 4:3). Not properly because in this way he would have been justified by works. But metonymically, faith is taken for its object (Gal 3:25), ie, for that which faith believes. (ie the promise, Gal 3:16)
Nor is this to wrest Scripture and to expose coldly the power of faith, as it is charged. Nay, no more clearly and truly can the genuine sense of that imputation be set forth. For since that thing which is imputed to us for righteousness ought to be our righteousness before God (that on account of which God justifies us), nor can faith be that, it is clear that this phrase is to be taken metonymically with regard to the object.
