The separation of Church from Synagogue was not a one-time act, but a long-lasting, multilayered, and diversified process. The attempt to explain this process, namely the process of parting of the ways between Judaism and Christianity in the years 30-313 AD, constitutes the main research subject of this publication. The aim of this study is the presentation of the dynamism of Christian-Jewish relations in the first three centuries of the existence of the Church, taking into account mainly historical and theological (but not the only) factors which influenced these relations and finally led to the creation of two separate religions. The two religions existing side by side were in many aspects connected with each other mostly because both originated from biblical Judaism.

Most commentators view the Epistle of Jude as a parenetic text. The commentary Expecting for the Mercy highlights its soteriological and Christological contents. This has been possible by taking a structural approach to the text and showing that its structure is chiastic, with Jude 1415 at its centre a description of the eschatological judgment foretold from the beginning of the world. The judgment is seen primarily as a time to show mercy to the faithful. Knowing this, the believers should also show mercy to the straying. Placing Jude 1415 at the centre of the theological reflection has allowed us to reveal the hermeneutic perspective applied to interpret apocalyptic texts. The narrator interprets this kind of texts from the Christocentric angle, just like all other writings belonging to the Jewish tradition. In addition, he uses typology and the pesher method. The commentary is ecumenical, taking into account both Catholic and Lutheran perspectives.
