Throughout 1851, Fr. Libermann exchanged a series of letters with Mgr. Kobès, coadjutor to the Vicar Apostolic of the Two Guineas (Mgr. Bessieux). Three months before he died, Libermann wrote a long letter that can be seen as his apostolic and spiritual testament
Libermann exhorted us to practice charity at all times, to identify with those we serve and value peace, solidarity, justice, and freedom, which find their fulfillment in Jesus. His writings bring to life the principles behind Spiritan faith, mission and practices.
