This question is not easy to answer in itself, since people leave churches for different situations. But, before continuing, I want to tell you that this article is not based on “changing the congregation”, but on “abandoning the Christian faith”, “ceasing to be Christians” or as many say “returning to the world”.
To the question of the title of this article we will find an ocean of answers. But, if we were to answer in order of priority we should start with “the doctrine”. Yes, people leave the church mostly because of doctrinal problems, because they feel that in the place where they congregate the Bible is not being taught as it should be taught.
