Israel and the Church in the Exegetical Writings of Hippolytus.

In one of its many polemical passages, the Epistle of Barnabas argues strenuously against 'some people,' apparently Christians, who claim that both Jews and Christians enjoy a covenantal relationship with the God of Israel: I am asking you this as one who is from among you and who loves each and every one of you more than my own soul: watch yourselves now and do not become like some people [τινες] by piling up your sins, saying that the covenant is theirs and ours [η διαθήκη εκείνων και ημων]. It is ours [ημων μέν]! As for them, they permanently lost it in this way, when Moses had just received it. (Barn. 4:6-7) [ABSTRACT FROM AUTHOR]
