lol hey Jesus ate with sinners, why can't we? lol there is just something about sitting down for a meal together that makes it more friendly.
Just remember to bless ALL the food, hey if they didn't want you to do it then they shouldn't have invited you to go.
However there is one letter from Paul that concerns me, How does this line up with being nice to strangers and basic hospitality? Is it just a case in point for that time period are do we still apply it today?
2 John 1
Beware of Antichrist Deceivers
7 For many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist. 8 Look to yourselves, that we do not lose those things we worked for, but that we[c] may receive a full reward.
9 Whoever transgresses[d] and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son. 10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; 11 for he who greets him shares in his evil deeds
