1 Corinthians 8:1-2

Now about food sacrificed to idols, we know that we all have knowledge [concerning this]. Knowledge [alone] makes [people self-righteously] arrogant, but love [that unselfishly seeks the best for others] builds up and encourages others to grow [in wisdom]. If anyone imagines that he knows and understands anything [of divine matters, without love], he has not yet known as he ought to know.
