Sometimes the implication of the question is that only those belonging to a particular type of church can be a Christian. As a Bible-based organisation, BF refuses to go along with that. People are saved on the basis of faith in Christ alone, not on the basis of whether they belong to a particular church or denomination. Neither can it be said on the basis of Scripture that belonging to a particular church prevents someone from coming to faith in Christ, even though there may be real differences with the teaching of some churches. Thankfully God is bigger than that, otherwise those such as John Wycliffe and Martin Luther might not have come to faith.
