The author asks whether the criteria for Catholic theology presented by the International Theological Commission’s Theology Today (2011) are meant to constitute “walls” that seal out or “windows” that open to the rich reality of God’s dialogue with humanity through creation and history. Careful exegesis leads the author to conclude that the document, while including restrictive paragraphs, intends to open up perspectives for a legitimate plurality of theologies within the living tradition of the Catholic Church. The article ends with a nuanced evaluation and highlighting of the document’s strong and weak points.
