The paper explores the two major contributions of Patristic Studies towards Biblical Studies. In the field of textual criticism, patristic quotations (direct quotations or allusions) from the Old Testament (Hebrew text or the LXX in the days of the fathers) and the New Testament represents a unique category of witnesses in the reconstruction and the tracing of the transmission history of the Biblical texts, albeit the massive manuscript witnesses available already. In order to use this massive data effectively and adequately, scholars have to first ascertain the quotation principles of the fathers and the biblical texts used in their days. History of interpretation is another important contribution that Patristic Studies renders to Biblical Studies. Modem biblical interpretation is predominated by historical-critical interpretation, but patristic interpretation emphasizes "multiple senses of the Scripture." Interpretation of the inspired text aims not at decoding the historical element of the text, but at the unfolding its spirituality. The massive data of patristic literature makes it unaffordable for average people to appreciate its value. The catenae approach of "Ancient Christian Commentary on Scripture" is the best means to present the interpretive insights of the church fathers to modem people
