With regard to food sacrificed to idols, we know that “we all have knowledge.” ¹  Knowledge puffs up, but love builds up.

For you were made rich ¹  in every way in him, in all your speech and in every kind of knowledge ²  –

So by your knowledge the weak brother or sister, ¹  for whom Christ died, is destroyed. ² 

For one person is given through the Spirit the message of wisdom, and another the message of knowledge according to the same Spirit,

Love never ends. But if there are prophecies, they will be set aside; if there are tongues, they will cease; if there is knowledge, it will be set aside.

But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled.

For if someone weak sees you who possess knowledge dining in an idol’s temple, will not his conscience be “strengthened” ¹  to eat food offered to idols?

And if I have prophecy, and know all mysteries and all knowledge, and if I have all faith so that I can remove mountains, but do not have love, I am nothing.

Now, brothers and sisters, ¹  if I come to you speaking in tongues, how will I help you unless I speak to you with a revelation or with knowledge or prophecy or teaching?
