The paper deals with problem of interrelations between barbarians and Christian Church in Roman Gaul of Vth c. a. d. Invasions of barbarians impaired to the Church. However Christian Church was not persecuted systematically and regularly, it was not a part of barbarian#s policy. More often barbarians persecuted servants of Church on suspicion of treason and for their active social position against new lords. Attitude of Christian Church to barbarian people was not negative. Moreover, сhristian writers often praised barbarians and considered them as a part of Divine Providence. Thereby Christian Church promoted conciliation between Romans and barbarians. Goodwill of the Church led to beginning of adaptation of certain barbarian nations to Catholicism in the end of Vth century.
