"Otherwise grace is no more grace," since it is bestowed on us, not because we have done good works, but that we may be able to do them.
Saint AugustineWhat the universal Church holds, not as instituted [invented] by councils but as something always held, is most correctly believed to have been handed down by apostolic authority. Since others respond for children, so that the celebration of the sacrament may be complete for them, it is certainly availing to them for their consecration, because they themselves are not able to respond.
