After the liberation of France it was relaunched, and at first had considerable success as the organ of the Popular Republican Movement.

Francisque Gay, future publisher and editor of L'Aube, launched the weekly La Vie Catholique in October 1924.

La Vie Catholique was independent, and after 1926 was hostile to the right-wing Action Française movement, although in 1928 Gay asserted that it was not involved in party politics.

In the first two years the paper prospered, due in part to the popularity of the Popular Republican Movement, in part to the fact that its rival Catholic daily, La Croix, did not appear for six months after the liberation of Paris.
