There are many who occasionally attend church and who are trying experimentally to be Christians, yet are unable to identify well or define accurately the central truths of Christian teaching. The knowledge they have of the Christian tradition may have come chiefly through hymns. Their strong and sincere feelings are not matched with serious biblical or historical reflection on those feelings. Religious feelings are, indeed, crucial to the deeper learning of Christian truth, but they easily become superficial and narcissistic if the mind of Christ is not a mentor to natural religious impulse. The loss of center in Christian education is arguably due to a serious default of pastoral leadership; when the teaching elder does not teach, the effect is felt throughout the entire Christian congregation.
