The call to holiness is not merely a theological idea but a deep and abiding invitation that echoes through the pages of Scripture and the history of the Church. Rooted in the Old Testament, the concept of holiness finds its fullest expression in the life and teachings of Jesus Christ. From the earliest moments of salvation history, God's desire has been to create a people for Himself, a holy nation set apart to live in His presence. The call to holiness is universal, extending to every baptized Christian, regardless of age, gender, or state of life.
