ACC ~ 1 Peter 4 v9
RECEIVE YOUR NEIGHBOR AS IF CHRIST. CHRYSOSTOM: If you receive your neighbor as though he were Christ, you will not complain or feel embarrassed but rather rejoice in your service. But if you do not receive him as if he were Christ, you will not receive Christ either, because he said: “Whoever receives you, receives me.” If you do not show hospitality in this way, you will have no reward. Abraham received passers-by and travelers just as they were. He did not leave them to his servants. On the contrary, he ordered his wife to bring flour, even though he had domestic help. But he and his wife wanted to earn the blessing, not only of hospitality but of service also. This is how we ought to show hospitality, by doing all the work ourselves, so that we may be sanctified. CATENA.
WITHOUT GRUMBLING. THEOPHYLACT: Note that when Peter mentions love he immediately goes on to talk about offering hospitality without grumbling. That is a sure sign of what love is. COMMENTARY ON 1 PETER.
