Speaking as a former Christian, I recall how believers would repeat one another's words or sermons. Therefore, Christian testimonies regarding being "born again by the Holy Spirit" frequently sound similar to one another. The biblical doctrine of being "born again" is one that many Christians have been indoctrinated to accept. When I was a Christian, it was what I was raised to believe. However, the theological doctrine of being "born again" is widely known to be from Protestantism, and it isn't adhered to by Roman Catholics.
As a matter of fact, Catholics claim that their church is the one and only "true church," and salvation comes only through Christ and his Catholic Church (
source). Meanwhile, most Protestants claim that the true Christian church is universal and includes all believers in Jesus, despite their church affiliation. Is salvation in Jesus conditional or not? Well, the answer depends on which Christian you ask.
The truth is, if you ask a group of diverse Protestant Christians the same theological question, you will get different answers, and all of these Christians will use the Bible to justify their answer, despite the fact that their answers are obviously different. You could ask the Catholics, Orthodox Christians, Anglican Christians, or Protestant Christians. If you go the way of the Protestants, then do you ask the Baptists, the Methodists, the Pentecostals, or the Presbyterians, or do you choose from the
hundreds of other Christian churches?
There has always been a lot of division among Christians who believe a different interpretation of the Bible, but most Christians like to claim that their interpretation of the Bible is the correct one and other Christians are wrong in their interpretation of the Bible. They often bicker and debate with each other over what they think the Bible actually teaches. Why should unbelievers believe the Bible is accurate if Christians can't even agree on what it says? Christians can't even agree which one of their churches is the "true church."
