The Presentation begins this month and reminds us how Jesus is not only the sign of the New Covenant, or agreement, with God but that he is also connected, intimately, with the Old Covenant, going right back to father Abraham.
In the early days of Christianity there were those who found the God of the Old Testament too angry and bloodthirsty to see any similarities with the God of whom Jesus speaks.
But the Gospels go to great lengths to make it very clear that Jesus walks out of the Old Testament and begins the New Testament.
There is no separation, only continuity.
The God of the Old Testament is just as loving and caring as in the New, and the God in the New Testament can be just as angry and judgemental, when his laws are cast aside, as in the Old.
