The article offers a detailed analysis of Prawdy wieczne (Eternal Truths) by Carlo Gregorio Rossignoli, an Italian Jesuit, focusing on its theological content and its function as a meditative text rooted in Ignatian spirituality. The work, first translated into Polish in 1701, is examined as a synthesis of catechism-based doctrinal teaching and Jesuit methods of spiritual exercises. Szczukowski explores how Rossignoli structures his reflections on creation, the purpose of life, sin, and the four last things – death, judgment, hell, and heaven – through a dual lens: as catechetical instruction and meditative practice. The article argues that Rossignoli’s approach goes beyond didactic exposition, offering a deep, prayerful engagement with Christian truths that aim to inspire personal conversion and spiritual vigilance. Through references to earlier catechisms, patristic literature, and the Spiritual Exercises of Ignatius of Loyola, Rossignoli constructs a work that combines doctrinal clarity with introspective, affective meditation directed at achieving salvation.
