of Ezra and 2 Book of Baruch. Such a rich comparative material contributes to the novelty of the book and enables the reader to discover both the similarities and differences between Paul, Greco-Roman and Jewish authors. The study analyzes Romans 8 in its rhetorical context and brings to light the novelty of the Pauline view of the Spirit. The apostle portrays it in its primary cognitive-ethical and communitarian function of making the believers similar to Christ and inculcating in them the Lord's mindset and attitudes. Paul presents the Spirit as dwelling within a person, similarly to God inhabiting the Jerusalem temple, and as the mediator of the resurrected life. In the original Pauline take the Spirit enables a close union between God and human beings in which the latter keep their freedom and distinctive personal traits.
