The apostolic letter "Amoris laetitia" has sparked a lively discussion. While many readers have perceived the letter as liberating, it has become a subject of intense debate for some due to a narrowed perception. Cardinal Kasper points out that "Amoris laetitia" represents a creative renewal of tradition grounded in the Gospel and incorporating the Second Vatican Council, which takes up and cautiously advances the positions of the recent pontificates. In the service of the "joy of love," Kasper contributes constructively to the discussion. He highlights the various aspects of the letter and defends it against a one-sided interpretation.
