The new 3 1/2 foot wall relief over Luisa's tomb in the Church of St. Mary the Greek, was created by Professor 'Vincenzo Petrizzelli of Corato. The relief depicts the Crucifixion of Christ with rays of light descending upon Luisa. Luisa is smiling with her heart exposed and the writings of the 36 Volumes laying about her. In prayer, she holds the Rosary in her left hand. The Fiat is clearly seen in gold above her head superimposed over a map of the world. The Church is represented to the right of her. The word, "Eccomi" (Here I am), in copper tubing, is placed in front of the tomb. The unveiling of the relief took place on 4 March 2004, in honor of the 57th Anniversary of Luisa's entrance into Heaven. Fr. Sergio Pellegrini, the Pastor of St. Maria the Greek Church in Corota, celebrated a special Mass on the occasion. Sr. Assunta, co-foundress of the Association Luisa Piccarreta, attended.

Saint Mary the Greek Church holds great significance in the life and death of Luisa Piccarreta. Her last confessor up to the time of her death was Father Benedetto Calvi, Parish Priest of Saint Mary the Greek Church. It was in this Church that Luisa, when she was nine years old, received First Communion and the Sacrament of Confirmation on the "in Albis" Sunday of 1874. Luisa used to remain in Saint Mary the Greek Church for hours at a time, kneeling motionless, engrossed in profound contemplation. At the age of 18, Luisa became a tertiary Dominican with the name of Sister Magdalena. At that time, the Parish Priest of Saint Mary the Greek, was promoting the Third Order, and Luisa was one of the first to become a tertiary. Archbishop Mons. Addazi obtained permission from the Holy Office (5-11-1962) to transfer the mortal remains of Luisa to inside Saint Mary the Greek Church with the internment occurring on July 3, 1962.
