The Bible is God revealing Himself to us - His own inspired, inerrant, and infallible testimony of Christ, a perfect treasure of divine instruction for life.
There is one and only one living and true God - infinitely holy, eternal, all-powerful, and all-knowing, revealed perfectly as Father, Son, and Holy Spirit, and thus deserving our highest love, reverence, and obedience.
Man represents God's crowning work of creation - made in His own image and given the freedom of choice, initially innocent of transgression yet falling as a race into a nature of sin from which freedom through forgiveness is only possible by God's grace.
Man's needed forgiveness is offered freely to all who personally receive Jesus Christ as Lord and Savior, who by His death and resurrection secured eternal redemption for each believer. There is no salvation apart from personal faith in Christ.
Salvation is the ultimate purpose of God, secured by election not inconsistent with man's free will and setting all true believers into a love relationship with Him in Christ by which they are held firmly for eternity in a state of grace.
The church may be considered both universal and local, including not only all of the redeemed of all the ages but also autonomous bodies of baptized believers (each responsible and accountable to Christ as Lord) connected in community by faith for fellowship, worship, discipleship, service, and witnessing.
The local church should observe the biblical ordinances of baptism (the water-immersion of a believer symbolizing the work of Christ in redemption as well as the fruits of redemption in his life) and the Lord's Supper (the obedient and regular partaking of the bread and the fruit of the vine memorializing the death of Christ yet in anticipation of His return).
Sunday represents "The Lord's Day," to be observed by the local church in commemoration of the resurrection of Christ in activities of worship and spiritual devotion.
