Well, preaching doesn't have to be a negative thing. But it usually is. And it's usually associated with people that do try and make people feel guilty. They, I'd assume, think that they are the "authentic" Christians. But some of us have come to hate Christianity because of those types of preachers. And... it's usually them that get caught having affairs or exploiting people for their money. But what can you do? They are the most visible Christians, because they on the radio and TV.
You raise a very important point. What you are seeing with this kind of preaching and this kind of guilt and this kind of verbal test of authenticity is a resurgence of anti christ, but this is expected. We're supposed to be fighting against anti christ over generations. It is part of a plan alluded to by various NT writers. Your pain was expected, anticipated and part of the program. It is part of our fight.
Christianity is like a laboratory for resolving how to unify people. The whole religion is designed to have fragmentation within it which challenges us to forgive each other. Its on purpose. This comes from the 'Gnostic' element which is evident in the NT writings saying that God and give wisdom to anyone. From the beginning it was expected that people would disagree strongly. The religion seems designed to bring out the disagreement in people, the pride, the animosity, the confrontations and then deal with them with forgiveness. Its just like how laboratories operate. We incorporate a miniature version of the world's problems into the religion where we can learn to fight it in miniature, and we do this over generations of Christians. It is like thousands of simulations. In Christianity the anti christ is to be treated like an oyster treats an irritant. When Christians learn to do this such begin to win and to defeat antichrist. When they don't do it, anti christ makes a resurgence. You see the kinds of things you're seeing today. Therefore Christianity acts as a laboratory to see what works -- what gets people to unify in spite of differences. Its History can be read like a laboratory manual.
So why do I think this was purposely done? I guess I'll just list a few of the relevant indicators in the NT that talk about this.
[Mat 16:17-18 NIV] 17 Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. 18 And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.
[Mat 10:34-38 NIV] 34 "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. 35 For I have come to turn " 'a man against his father, a daughter against her mother, a daughter-in-law against her mother-in-law-- 36 a man's enemies will be the members of his own household.' 37 "Anyone who loves their father or mother more than me is not worthy of me; anyone who loves their son or daughter more than me is not worthy of me. 38 Whoever does not take up their cross and follow me is not worthy of me.
[Mat 7:15-16 NIV] 15 "Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves. 16 By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles?
[Jhn 17:23 NIV] 23 I in them and you in me--so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me.
[Act 20:30 NIV] 30 Even from your own number men will arise and distort the truth in order to draw away disciples after them.
[1Co 15:28 NIV] 28 When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.
[1Jo 3:18-19 NIV] 18 Dear children, let us not love with words or speech but with actions and in truth. 19 This is how we know that we belong to the truth and how we set our hearts at rest in his presence:
[1Co 1:19 NIV] 19 For it is written: "I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate."
[1Co 11:18-20 NIV] 18 In the first place, I hear that when you come together as a church, there are divisions among you, and to some extent I believe it. 19 No doubt there have to be differences among you to show which of you have God's approval. 20 So then, when you come together, it is not the Lord's Supper you eat,
No, these are not the whole list but only a few to give an idea of what I am talking about. I could go on and on, because all of the scriptures in the NT are focused upon this. Christianity begins with the radical assumption that the Father can reveal things to individuals, that we must forgive, that we have power to forgive sins and that in order to take communion we must do so. I assert to you that it was anticipated that there would be friction, false teachings, evil leaders and people who didn't want to listen to sound principles. Christ is nevertheless expected to unify. The book Revelation describes Christianity as a war against various enemies, internal enemies described in its first chapters about the problems with seven churches. These internal enemies are in the symbols of John's revelation, and over the eons they are to be eventually destroyed by all church people unifying, answering Jesus prayer.
