Mary in the Mystery: The Woman in Whom Divinity and Humanity Rhyme (New City Press), is recommended by Fr Paul McPartlan at CUA. Leonie and I have written an Afterword and Foreword respectively. In the Foreword I write: “In poetry, the word rhyme refers to an echo or resemblance between two or more lines of the poem, particularly in the end of the lines – some way in which they sound alike whilst being different. The two natures of Christ, divine and human, are of course radically different. But in the Hypostatic Union the two natures converge on the same ‘end,’ the same ‘Word.’ This is divine poetry. The divine nature comes from heaven, and the human nature comes from Mary, like two kinds of music one above the other; they are ‘united without commingling,’ merging in one sound, one voice, one Gospel, one revelation.” The book is "an exercise in poetic theology, leading us into the mystery of Christ by exploring the wonderful harmony established in and through Mary between the divine and the human."
