Roma 1:6

1:6 You also are among them, ¹  called to belong to Jesus Christ. ² 

Roma 15:6

15:6 so that together you may with one voice glorify the God and Father of our Lord Jesus Christ.

[1:6]  ¹ tn Grk “among whom you also are called.” Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation. The NIV, with its translation “And you also are among those who are called,” takes the phrase ἐν οἳς ἐστε to refer to the following clause rather than the preceding, so that the addressees of the letter (“you also”) are not connected with “all the Gentiles” mentioned at the end of v. 5. It is more likely, however, that the relative pronoun οἳς has τοῖς ἔθνεσιν as its antecedent, which would indicate that the church at Rome was predominantly Gentile.

[1:6]  ² tn Grk “called of Jesus Christ.”
