Judaism and christianity/ Answering questions. Part 2

Leon Mazin. Messianic Center “Return to Zion” Israel.

0:20. Where do names the Old and New covenants come from? And are these two mutually exclusive covenants or are they part of the same covenant?
3:14. If the Jews reject Christ, do they continue to be in the covenantal relationships with God or have they fallen away and have no longer any connection with Him? Is there any link today between God and the Jewish people?
9:00. Who has to make a first step – the Church toward Israel or Israel toward the Church?
14:01. If Christ as a promised Messiah, called a head of the Church, then why is the Church supposed to return to the Old Covenant practices and not other way around?
