The Rule is the foundational spiritual and governance document of the Society of St. Vincent de Paul. First written in 1835 by Emmanuel Bailly and Francois Lallier, all Vincentians promise to do their best to live our Rule. This pocket-sized edition does not include Part II, International Council General, but includes Parts I and III in full. All Vincentians should have a copy of our Rule, and this one is an excellent version that you can carry with you and refer to often!
