TSK · Luke 5:29

As Jesus was having a meal in Levi’s home, many tax collectors and sinners were eating with Jesus and his disciples, for there were many who followed him.

So they prepared a dinner for Jesus there. Martha was serving, and Lazarus was among those present at the table with him.

If an unbeliever invites you to dinner and you want to go, eat whatever is served without asking questions of conscience.
