Let the churches preach doctrines, theories, philosophies to their hearts' content, but when it comes to worship, the real practical part of religion, it should be as Jesus says, "When thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret".
The kingdom of heaven is within us. The Jewish idea was a kingdom of heaven upon this earth. That was not the idea of Jesus.
It is an irrational claim to believe in the teachings of Jesus Christ and at the same time to hold that the greater part of his teachings have no application at the present time. If you say that the reason why the powers do not follow them that believe (as Christ said they would) is because you have not faith enough and are not pure enough-that will be all right. But to say that they have no application at the present time is to be ridiculous.
