I don't think any religion is full of Christians or has a lack of Christians. Is every Catholic a Christian? No, but I think there are some Catholics that ARE true Christians. Do I think every baptist is a true Christian? No. But I think there are some Baptists that are. It's not winning a lottery. It's believing and having faith that Jesus is Christ and letting the Holy Spirit guide and direct your life.
The question of asking if a group "has it" is a leftover from the WT. They want you to look for a group of people that HAVE the truth. They forget that Christianity isn't belonging to a religion.
That is a good answer. Let's get more specific.
What about Catholics who DO ignore parts of the Bible? Are they "true" Christians?
