76 These laymen, thus enlisted under the banner of Christ and completely obedient to the bishop who properly reserves to himself the final authority in the apostolate, and being in complete accord with the Catholics of Africa who look favorably upon these fraternal recruits, usefully bring to bear upon the recently established dioceses the full weight of their experience in Catholic Action and other social programs and in any other particular activities required in the apostolate. Further - and this is extremely beneficial - they are able to effect a speedier and easier union of their own national Institutes with countless other agencies that are international in scope. We are happy to congratulate them on the excellent work they are doing for the good of the Church.
