St Louis Marie's aim in all his missions was "to revive the Christian spirit through the renewal of the baptismal promises" (according to his earliest biographer, Joseph Grandet). Grandet adds: "And to help them to remember their undertakings, he had a formula of renewal printed, and those who could write were required to sign it" during a special ceremony which was the highlight of the mission. St Louis Marie speaks of the consecration which he proposes in his True Devotion to the Blessed Virgin as a "perfect renewal of the vows of Baptism".
Four printed copies of this Contract of Covenant with God have been preserved. Two of them, showing slight variations, are reproduced in God Alone - The Collected Writings of St Louis Marie de Montfort.
