Marie-Pauline Martin, also known as Sister Agnes of Jesus OCD (7 September 1861 – 28 July 1951) was a French Discalced Carmelite and Catholic prioress.

[citation needed] In 1897, with her sister's permission, Pauline helped edit Thérèse's spiritual memoir, Histoire d'une âme (Story of a Soul).

[5] In 1926, Pope Pius XI issued a controversial condemnation of the French right-wing group Action Française, led by the agnostic writer Charles Maurras.

Martin and her convent went beyond Pius's request, and communicated directly with Maurras, in an attempt to revert him to Catholicism.

[7] In 1939, after Pope Pius XII lifted the ban on Action Française, Maurras wrote the convent a letter, thanking them for their support.
