From the first pages of Scripture to the final vision of the heavenly Jerusalem, the drama of salvation unfolds within a world ordered toward worship. Creation itself is presented not merely as the backdrop for human history but as the primordial sanctuary in which God places His image-bearing creature to offer praise, obedience, and thanksgiving. The biblical narrative is saturated with cultic language, gestures, and institutions, all of which reveal that humanity's deepest identity is inseparable from its vocation to worship the living God. To speak of the biblical cultus is therefore not to isolate one theme among many but to approach the very center of divine revelation. Worship is not an ornament of religion; it is the form of the covenant relationship between God and His people. It is the means by which God sanctifies humanity and draws it into communion with Himself.

This book seeks to explore the biblical cultus-its sacrifices, priesthood, and modes of worship-from a traditional Catholic perspective, attentive to the unity of Scripture and the continuity of God's saving plan. Such an exploration requires a careful engagement with the Old Testament, where the cultic system is established and elaborated, and with the New Testament, where Christ brings this system to its definitive fulfillment. It also demands attention to the living Tradition of the Church, which receives, interprets, and actualizes the biblical cultus in her liturgy and sacramental life. The Catholic approach to Scripture is never merely historical or literary; it is theological, sacramental, and ecclesial. The Church reads the Bible as the Word of God entrusted to her, and she reads it with the conviction that the same Spirit who inspired the sacred authors continues to guide her understanding.
