'Believers' in the Bible

Yet when we are among mature believers we do speak words of wisdom; a wisdom not belonging, however, to the present age nor to the leaders of the present age who are soon to pass away.

But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.

But take care lest this liberty of yours should prove a hindrance to the progress of weak believers.
