This is unreasonable. The Holy Spirit is not the Bible and the Bible is not the Holy Spirit. Yet, the Holy Spirit will not direct a person to practice or believe anything that is opposite of what he caused to be written in the Bible. The direct operation of the Holy Spirit on the human heart is an old doctrine. It is one of the major points of Calvinism and it has been espoused by most denominations.
Today there are untaught members of the church who have accepted it.
We need to change to hold the baby boomers. As long as the basics of the Bible are not changed, then matters of opinion can be changed, according to what is best for most people, or according to the judgment of the elders. Kneeling for prayer, meeting in rented facilities, singing without song books, and such like do not change the basics of the Bible. Most congregations could improve their regular worship. However, a Christian worships God and his focus is not on himself.
