Christadelphians are known for their study and understanding of God's word. We differ from mainstream churches in that all are encouraged to learn about God for themselves, and to teach others. We are often criticised for having no paid ministry, but we all study and discuss the Bible individually and in groups, and no one's ideas are taken as gospel truth unless they can be proven from God's word. Some churches today are changing their beliefs to fit in with popular beliefs or community demands. The Christadelphians believe God never changes, and so neither will we ever change what God has taught. God does not change His mind because he wants humans to have whatever they want.
