"This is My Body" was inspired through a conversation that Fr. Pavone had with Dana about the comparison between the words "This is My Body" as used by Jesus to give us eternal life, and as used by abortion supporters to defend the taking of life. Fr. Pavone gave Dana the brochure that he had written about this comparison, and suggested that a song should be written to convey this powerful message. Within a few hours, Dana called him back and said that she had the song basically written! After subsequent meetings and sitting together at the piano, Fr. Frank and Dana were satisfied that the finished product would inspire pro-life people worldwide.
In the song, Dana plays the role of a woman who has had an abortion. Gretchen sings as a woman who believes in the "right to choose." And Mark plays the role of Jesus, who teaches us to sacrifice ourselves for others. They each do this using the same words, "This is My Body."
