Non-fiction, this work is part of a comprehensive biblical studies course, titled Il messaggio della salvezza, aiming to present the unity and development of salvation history through a theological and scriptural lens. The volume synthesizes key moments in the Old and New Testaments, with emphasis on God’s covenant, prophetic revelation, and the fulfillment of promises in Christ. Designed for use in academic, catechetical, or seminary contexts, the 5th edition (1969) reflects mid-20th-century Catholic biblical scholarship and pedagogy, contributing to a structured understanding of biblical theology.
