Church of England should teach the Old Testament

Here's one reason why some Christians perhaps struggle to understand Jewish identification with Israel. It's a short passage (para 81) from a report on interfaith relations and Christian mission due to be discussed at the Church of England Synod on Thursday. I should add the context is nothing to do with Jews and Israel but it is revealing, nonetheless:
"The Old Testament is sometimes seen as of lesser importance to Christian faith today, and in some churches it may only rarely be used in worship or teaching. The TaskGroup considered it crucial to reclaim the place of the Old Testament in church life. The way in which the chosen passages speak to the whole range of human life - to individuals, families, and societies; in times of stability and of disruption; in promise and warning, in reassurance and rebuke; strengthening convictions and undermining assumptions is striking."
