Catholic Commentary on Romans 4

"Against all hope, Abraham in hope believed and so became the father of many nations." (Romans 4:18)

The Father of All Who Believe

Paul turns to Abraham to demonstrate that justification by faith is not a novelty but the original pattern of God's dealing with humanity. What did Abraham discover? If Abraham was justified by works he had something to boast about, but not before God. What does the Scripture say? Abraham believed God, and it was credited to him as righteousness. He quotes Genesis 15:6, the moment of the covenant promise. The critical point Paul makes is temporal: Abraham was credited with righteousness while he was still uncircumcised. Circumcision came later, as a sign and seal of the righteousness he had already received by faith. Therefore Abraham is the father of all who believe, both circumcised and uncircumcised. The covenant was made with the believing Abraham, not the circumcised Abraham.

The promise to Abraham and his offspring that he would be heir of the world came not through the Law but through the righteousness of faith. If those who depend on the Law are heirs, faith means nothing and the promise is worthless. The Law brings wrath, but where there is no Law there is no transgression. Therefore the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham's offspring, not only those under the Law but also those who share the faith of Abraham, who is the father of us all.

Hope against Hope

Against all hope, Abraham in hope believed and so became the father of many nations. He faced the fact that his body was as good as dead, and that Sarah's womb was also dead. Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, being fully persuaded that God had power to do what he had promised. This was credited to him as righteousness. The Catechism identifies Abraham's faith as the paradigm of all theological faith: not the evidence of things seen but the confident trust in the faithfulness of the one who has promised (CCC 146). Against all human hope, in hope believing.

Living the Word

Brothers and sisters, Abraham did not weaken in faith when he faced the fact of his and Sarah's age. He faced it fully, and believed anyway. This is mature faith: not the avoidance of hard facts but the choice to trust God's promise in the full knowledge of contradicting circumstances. What promise of God are you facing that seems contradicted by the facts? Face the facts, as Abraham did. Then believe God, as Abraham did.

Prayer

Lord God, you called Abraham to believe against all hope and he believed and it was credited as righteousness. Give us Abraham's faith: fully aware of the obstacles, fully trusting in your promise, giving you glory because you have the power to do what you have promised. Through Christ our Lord. Amen.

Abraham Justified by Faith
(Genesis 15:1–7; Psalms 32:1–11; Hebrews 11:8–19)
What then shall we say that Abraham, our forefather, has discovered? If Abraham was indeed justified by works, he had something to boast about, but not before God. For what does the Scripture say? “Abraham believed God, and it was credited to him as righteousness.”* 4:3 Genesis 15:6
 
Now the wages of the worker are not credited as a gift, but as an obligation. However, to the one who does not work, but believes in Him who justifies the wicked, his faith is credited as righteousness. And David speaks likewise of the blessedness of the man to whom God credits righteousness apart from works:
 
“Blessed are they whose lawless acts are forgiven,
whose sins are covered.
Blessed is the man
whose sin the Lord will never count against him.” 4:8 Psalms 32:1–2 (see also LXX)
 
Is this blessing only on the circumcised, or also on the uncircumcised? We have been saying that Abraham’s faith was credited to him as righteousness. 10 In what context was it credited? Was it after his circumcision, or before? It was not after, but before. 4:10 Literally How then was it reckoned—being in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision.
 
11 And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but are not circumcised, in order that righteousness might be credited to them. 12 And he is also the father of the circumcised who not only are circumcised, but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised.
Abraham Receives the Promise
(Genesis 15:8–21)
 
13 For the promise to Abraham and his offspring that he would be heir of the world was not given through the law, but through the righteousness that comes by faith. 14 For if those who live by the law are heirs, faith is useless and the promise is worthless, 15 because the law brings wrath. And where there is no law, there is no transgression.
 
16 Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all. 17 As it is written: “I have made you a father of many nations.”§ 4:17 Genesis 17:5 He is our father in the presence of God, in whom he believed, the God who gives life to the dead and calls into being what does not yet exist.
 
18 Against all hope, Abraham in hope believed and so became the father of many nations, just as he had been told, “So shall your offspring be.”* 4:18 Genesis 15:5 19 Without weakening in his faith, he acknowledged the decrepitness of his body (since he was about a hundred years old) and the lifelessness of Sarah’s womb. 20 Yet he did not waver through disbelief in the promise of God, but was strengthened in his faith and gave glory to God, 21 being fully persuaded that God was able to do what He had promised. 22 This is why “it was credited to him as righteousness.” 4:22 Genesis 15:6
 
23 Now the words “it was credited to him” were written not only for Abraham, 24 but also for us, to whom righteousness will be credited—for us who believe in Him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our trespasses and was raised to life for our justification.
