It is unphilosophic and imprudent to disturb anyone's religious faith. It is only when the course of events or their own mental development creates doubts and disquiet--and even then they must come seeking more satisfactory answers to their questions--that higher teaching can be given. But even then the manner in which the latter is presented is important--that is, try not to bring it into collision with those parts of their faith which they still hold, be constructive and not destructive. In that way the new teaching can be presented as a higher octave of the old one or used for reform of the old one.
