These radio homilies, broadcast over a period of several decades, were collected and arranged solely according to their place in the Church’s calendar. This selection concerns the feasts of God, of Christ and of his Mother; the feasts of the saints could fill another volume: this one is already large enough. Naturally there is nothing systematic about the order in which the homilies appear, unless, that is, they are viewed from a higher perspective: then, indeed, constant themes do emerge—perhaps only a single theme—of which the individual items are only variations. For in the Christian Faith, after all, there is only one dogma, splitting like light into a rainbow of colors, or, like a living body, expressing itself in manifold members, each dependent on the others. Just as we cannot understand anything of Christ apart from the mystery of the Trinity, anything of the Church without faith in Christ’s divinity and humanity, anything of the sacraments apart from the bridal mystery between Christ and the Church, so too we cannot understand anything of the Christian life (or morality) without the Christian Faith (or dogma): orthopraxy and orthodoxy are two sides of the same coin. So it is that these homilies keep circling around the same center: the inexhaustible mystery of our one, indivisible Faith.
