ὁ Θεός, ὃς

The relative clause is anchored to "God" and states what he does in relation to both groups named in the verse.

It presents God's action as the reason the sentence can speak of one God who justifies both circumcision and uncircumcision by faith.

It does not by itself specify a different subject, and it does not require a separate doctrinal meaning beyond the clause's argument.

High: The verb is central to Paul's argument that the one God justifies both groups through faith.

Future active indicative assertion. states God's justifying action toward both circumcision and uncircumcision. Attached to the relative clause anchored to God. Governed by Paul's argument about one God and one way of justification. The future form carries the clause's assertion without making justification uncertain or merely delayed.

What action does Paul ascribe to God? God justifies both circumcision and uncircumcision through faith.

Direct: The future active indicative directly supports wording such as 'will justify.'

The future form should be read within Paul's argument about one God, not as a claim that justification is only future or uncertain.

Future tense always means uncertain or merely later: The future form can assert what God will do; timing and theological force must be read from the argument.

The witness reads "ὃς δικαιώσει περιτομὴν ἐκ πίστεως, καὶ ἀκροβυστίαν διὰ τῆς πίστεως," in Romans 3:30.

The lemma is δικαιόω, which in this context carries the sense of justify or declare righteous.

The future indicative fits a confident statement about what the one God does for both circumcision and uncircumcision, and the surrounding prepositional phrases shape how that action is described.

Paul's point is that one God justifies both groups through faith, so the grammar supports a unified divine action across both audiences.

This aligns with Paul's broader presentation of justification as God's gracious act received by faith and not as a ground for boasting.

For teaching and translation, the form can be rendered as a sure declarative statement about God's justifying action, while keeping the focus on the verse's argument.

Do not derive a separate theological system from the tense alone, and do not treat future tense as proof of timing beyond the sentence's present argument.
