 Cohen had never known a priest besides Lamennais and was confused as to in whom he could confide.He was introduced to Marie Theodor Ratisbonne, a fellow Jewish convert, who, in turn introduced him to the Abbé Legrande.Under his instruction, Cohen was trained in the Catholic faith and was baptized, with the baptismal name of Marie-Augustin-Henri, on 28 August, the feast day of his namesake, St. Augustine.
