Bibliology: That the Bible in all of its books, and in every verse and in every part is fully inspired of God. (2Tim.3:16; 2Pet.1:20-22).
--It is our sole and final authority in all matters of faith and doctrine.
Soteriology: Salvation is by faith in Christ and by faith in his sacrifical work on the Christ--by faith and faith alone.
More accurately it is by grace through faith (Eph.2:8,9)
It is by grace for God provided salvation entirely by his grace.
It is by faith for the only way to accept the gift of God is by faith; it is impossible to receive his gift by works. One cannot work for a gift.
It is the substitutionalry work of Christ that saves, whereby Christ came a substitute for us suffering the penalty of our sin on our behalves--the just for the unjust that he might bring us to God being put to death in the flesh but quickened by the spirit.
It is the atoning work of Christ, Christ making an atonement for our sins--an official payment with his shed blood that the Father would be satisfied with the payment of the penalty of our sins.
It demands faith, repentance, the new birth, conversion, and regeneration. all of which are similar in nature but describe a different aspect of the salvation process.
Christology:
Jesus Christ is God--He is fully God, the second person of the trinity. He is eternal--existng before the foundations of the world--having no beginnng and no end: the alph and the omega, the beginning and the end.
He was born of a virgin, became God incarnate; became fully man and fully God at the same time. He died, was buried and rose again the third day according to the Scriptures, and demands all to believe on him for salvation. He is the only way by which man may go to heaven (John 14:6)
Theology:
This is the study of God (proper). God is a triune being--three persons in one God--God the Father, God the Son, and God the Holy Spirit. All three have their own personality. They are three separate persons, and yet at the same time make up only one God. This is a mystery which must be taken by faith. God created all things. He is a God of Love, Justice, Mercy, Holiness, Omnipotence, Omnipresence, Omniscience, and has many other attributes. None of his attributes contradict each other, but full compliment one another. He is fully God, having need of nothing. It is God that we depend upon for all things. He is the potter and we are the clay. Through Jesus Christ we may develop a relationship with him. True Christianity is not a religion but a relationship.
Pnemeunatology: The doctrine of the Holy Spirit is much misunderstood. The Holy Spirit is a person--the third person of the triune Godhead. He is not just an influence but an actual person. He is known in Scripture as the "Comforter" which Jesus promised would come after Him, and would indwell every believer who believed on him. We do not believe that there is a subsequent blessing, but rather that the Lord commands the Christian to be filled with the Holy Spirit on a daily basis by submitting to Him.
Demonology and Angeology:
The devil (Satan) is a real person. He is not omnipresemt, but ubiquitous. That is, he seems to be everywhere because of the legions of fallen angels (demons) that he has under his control and are working for him. Are all these are real spirits working for evil in this world today, working for Satan against the will of God. The Bible commands us to "resist the devil and he will flee from you."
Angels on the other hand, are God's spirits sent to minister to the saints. (Heb.1:13). They live in heaven in the presence of God, to do God's bidding. They also are spirit beings.
Ecclesiology:
God's chosen vessel of doing his will today is through the local church. Most of the epistles were either written to a local church or to a pastor of a local church. It is a God-ordained institution, whereby saved individuals are baptized and then voluntarily need to join in order to carry out the Great Commission and join in celebrating the two ordinances of Christ: the Lord's Supper and the ordinance of Baptism. The church, per se, cannot save. But it is God's vehicle whereby the Great Commission was given and it is instrumental in the salvation of others, and in the instruction and fellowship of fellow believers.
Eschatology:
The study of last thngs cannot be ignored as the Bible devotes a great deal of it pages to this important subject. Christ is coming agan. He first is coming for his own, when the first resurrection takes place. This is called the rapture. Immediately after the Great Tribulation will take place and will last for seven years. then Christ will return agan, at which time he will set up him Millennial Kingdom. At the end of that one thousand period, Satan will rebel against God one final time and will be defeated by fire coming out of Heaven. Then the Great White Throne Judgement will take place. This is, of course immediately following the second resurrection.
Eternity will begin immediately after that.
Since this is all from memory, I may have missed one or two doctrines. But these are some of the most important doctrines that are fundamental to our faith.
