I was never asked that question but I have rolled it around in my head since learning of it's popularity.
I think I would claim no comment. Tell the elders that wether or not God is using the FDS is between God and the people who claim to be the FDS. Since I have no way of confirming their claim of spiritual appointment, claims that men have been making for thousands of years, claims that all have exactly one thing in common - NO EVIDENCE, then for me to chime in on the subject would amount to heresay.
To clarify their question... "If you are asking wether or not I put my trust in man, I prefer not go beyond the things written:
In God I have put my trust; I shall not be afraid. What can flesh do to me? - Psalms 56:4
It is better to take refuge in Jehovah than to trust in earthling man. - Psalms 118:8
Do not put YOUR trust in nobles, nor in the son of earthling man, to whom no salvation belongs. - Psalms 146:3
