The Church has maintained a belief in the fundamentals of the faith since its beginning. It still believes that the Bible is the infallible Word of God. It believes that Jesus Christ was God become man. It believes that He paid the penalty for our sins by dying on the cross, and rising from the dead on the third day. It believes that Christians have a responsibility to share the gospel that Jesus is the only hope for salvation, from an eternity in hell, and for an eternal home in heaven. It believes that Jesus Christ will come again to this earth.
The congregation has changed over the years but it is still like its forbears seeking religious freedom to study and practice what the Bible says. It could still meet at the First Church building (if it had continued) for it remains evangelical in holding to the same conversion experiences of that 1858 revival. The original "Little Red School House" has also gone but the Port Washington Christian School continues its theistic teaching in its own one room setting.
