1. What is rudeness?
5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 1 Corinthians 13:5
2. Where and how is it used in the rest of God’s Word?
36 If anyone is worried that he might not be acting honorably toward the virgin he is engaged to, and if his passions are too strong and he feels he ought to marry, he should do as he wants. He is not sinning. They should get married. 1 Corinthians 7:36
13 Judge for yourselves: Is it proper for a woman to pray to God with her head uncovered? 14 Does not the very nature of things teach you that if a man has long hair, it is a disgrace to him, 15 but that if a woman has long hair, it is her glory? For long hair is given to her as a covering. 16 If anyone wants to be contentious about this, we have no other practice—nor do the churches of God. 1 Corinthians 11:13-16
20 So then, when you come together, it is not the Lord’s Supper you eat, 21 for when you are eating, some of you go ahead with your own private suppers. As a result, one person remains hungry and another gets drunk. 22 Don’t you have homes to eat and drink in? Or do you despise the church of God by humiliating those who have nothing? What shall I say to you? Shall I praise you? Certainly not in this matter! 1 Corinthians 11:20-22
3. Why is it unloving to be rude?
9 Love must be sincere. Hate what is evil; cling to what is good. 10 Be devoted to one another in love. Honor one another above yourselves. Romans 12:9-10
30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ 31 The second is this: ‘Love your neighbor as yourself.’[b] There is no commandment great. Mark 12:30-31
13 You, my brothersand sisters, were called to be free. But do not use your freedom to indulge the flesh; rather, serve one another humbly in love. Galatians 5:13
3 Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, 4 not looking to your own interests but each of you to the interests of the others. Philippians 2:3-4
12 So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets. Matthew 7:12
