I think it's obvious that many of the biggest and most prominent churches as institutions are opposed to the teachings of Jesus.
Look at churches that protect sex abusers. Look at churches that attack people "not like them." People who REJECT the parable of the Good Samaritan are NOT followers of Jesus.
The loudest churches are always on the attack. They do not know love and therefore do not know Jesus.
They are frauds.
This is obvious and this is why people, especially young people, are turning away from churches and why churches characterized by hate have no future. And deserve no future.
