The article presents the subject of God’s love in Cardinal Wyszyński’s teaching. Primate Wyszyński puts God’s love at the very center of his theological thought. The theme of God’s love is discussed in seven sections: the first of them refers to the most famous words of Saint John’s “Deus Caritas est” (1 Jn 4:8,16), which are a short and brief definition of God; the second section develops Cardinal Wyszyński’s statement that there was a “time” in which only Love existed; the third section concerns the impartation of God’s love; fourth section describes the love of the Father; fifth section speaks of the greatest Love, which is the Incarnate Son of God, Jesus Christ; section six focuses on the Holy Spirit, who is the Spirit of Love; the last section speaks of Mary, Mother of Beautiful Love. The whole ends with the summary. In his teachings on the love of God, Cardinal Wyszyński started with the inner life of the Triune God, with the Person of the Father, and then focuses on the salvific mission of the Son of God and the sanctifying action of the Holy Spirit. In this way, he appreciates both the category of God the Father and God as a Father full of love.
