You are incorrect.
You may be referring to cultural Christians, but not authentic Christians.
Your description of Christian behavior does not at all match many of the people I know of.
People who refer to themselves as “real” or authentic Christians; people who deserve to wear the badge of self-righteousness most Christians confer upon themselves are people who on a regular basis at the very least obey every one of these commands:
• Attend church every Sabbath or more frequently (Deut 5:12).
• Observe all the rules and regulations, sacraments, etc. (Your church).
• Disposed of all your worldly goods for the benefit of the church and the poor (Acts 2:45; Lk 12:33).
• Visit on a regular basis all those incarcerated felons, murderers, etc. (1Peter 3:19; Mt 25:24).
• Forgive everyone who sins against you and never hold a grudge or be angry with anyone (Mt 6:12-15).
• Don’t plan for the future (Mt 6:34).
• Don’t save money (Mt 6:19-20).
• Don’t become wealthy (Mk 10:21-25).
• Don’t work to obtain food (Jn 6:27).
• Give unquestionably to anyone who asks of you even if it’s your last dollar (Mt 5:42).
• Turn the other cheek when someone offends you to allow him to strike you again. (Mt 5:39).
• Judge not (Mt 7:1; Lk 6:37).
• Refuse to divorce your mate unless fornication was involved (Mt 19:9).
• Don’t have sexual urges (Mt 5:28).
• Continuously have sex with your mate (1Cor 7:5) (How you could do this and continuously pray is a mystery to me!)
• Make people want to persecute you (Mt 5:11).
• Let everyone know that you are better than they are (Mt 5:13-16).
• Hate your parents, siblings, and spouse (Lk 14:26).
• Never take a fellow Christian to court (1Cor 6:1).
• Give more than the judgment if you lose a lawsuit, (Mt 5:40)
• Walk two miles if someone forces you to walk a mile, (Mt 5:41).
• Uncover in church if you are a man and cover your head if you are a woman (1Cor 11:5-6).
• Take money from those who have little and give it to those who have a lot (Lk 19:23-26).
• If someone robs you, don’t try to get it back (Lk 6:30).
• Cut your hair closely if you are a man (1Cor 11:14).
• Never wear a lot of jewelry if you are a woman (1Tim 2:9; 1Peter 3:3).
• Fear God (Ps 103:11 plus a lot more).
Do you do all that?
