Some other Protestants hold that only believers who believe in certain fundamental doctrines know the true pathway to salvation. The core of this doctrine is that Jesus Christ was a perfect man, is the Son of God and that he died and rose again for the wrongdoing of those who will accept the gift of salvation. They continue to believe in "one" church, an "invisible church" which encompasses different types of Christians in different sects and denominations, believing in certain issues they deem fundamental, while disunited on a variety of doctrines they deem non-fundamental. Some evangelical Protestants are doubtful if Roman Catholics or Eastern Orthodox can possibly be members of this "invisible church", and usually they reject religious (typically restorationist) movements rooted in 19th century American Christianity, such as Mormonism, Christian Science, or Jehovah's Witnesses as not distinctly Christian.
