Hebrew Scripture for Christian Preaching
One of the Early Church’s most famous heretics, Marcion, decided that the God of the Old Testament and the God revealed in Christ were incompatible. In what was arguably the first attempt to create a Christian canon of scripture, he sought to dispose of the OT entirely and purge OT references from the New Testament. Notwithstanding Marcion’s many other theological quirks, his objection to the OT is perhaps something we can still relate to. It is still not uncommon to hear a Christian today describe themselves as a ‘New Testament Christian’ as opposed to an ‘Old Testament Christian.’ Apart from the apparent dichotomy of legalism and grace between the testaments there are also ethical issues raised by the text: genocide, incest and misogyny, among others. These and other perceived problems translate into a general neglect of the OT as a source for preaching and, when it is used, uncertainty in the appropriate way to do so. Three problems confront any Christian wanting to preach from the OT: how to relate the OT and NT, how to correctly exegete the OT, and how to discover the contemporary relevance of any particular OT passage.
However, evangelicals are rightly restrained from following Marcion’s lead, primarily by the NT itself. Verses such as Luke 24:44 and John 5:40 show Jesus clearly stating that the OT is in some significant sense about him. Numerous passages in Acts reveal that apostolic preaching repeatedly argued that Christ fulfilled the OT. The gospels, epistles and Revelation are laced through with OT quotations and allusions to the OT scripture. In addition to this, the historical record clearly shows that the primary source for the theological reflection of the early church on Jesus Christ was the OT. So by using the OT as a source for preaching we are following Christ, the Apostles, the authors of the NT and the Early Church Fathers.
Part of the problem arises in the fact that Christ and his early followers drew upon a deep and established tradition of scriptural interpretation that modern scholars only have limited access to and the ordinary Christian has no understanding of. Not only so, but many of the hermeneutical devices employed quite satisfactorily in the 1st century appear dishonest and unscientific in the 21st. If the early church relied on Second Temple era hermeneutics to make Christian sense of the OT should present day preachers use the same methods or can modern hermeneutics also find that the OT speaks of Christ?
