I hold to the Westminster Confession of Faith (American revision). This is a short summary in my own words of what I believe (Oct 2016):
God reveals Himself to mankind by General or Special Revelation. In General Revelation, God reveals Himself through created things in nature and the consciences of men. Such revelation is non-propositional in nature and is grasped by intuition. All of mankind received this revelation yet chooses to suppress the truth of God in unrighteousness. General Revelation is sufficient to condemn those who reject it yet is powerless to save anyone. As it is non-propositional, General Revelation does not provide anyone with justified beliefs and therefore natural theology is fallacious and erroneous.
Special revelation is God's revelation given in propositional content to His people. It is not general, and thus not given to all people. Although propositional in content, it adopts many forms and genres. While special revelation encompasses all revelation given from God and thus includes the diverse prophecies from God's prophets through the ages beyond the pages of Scripture, all of special revelation that is of importance as God's definite revelation to us is found today in the Scriptures and no where else, all other forms of revelation having ceased with the finality of Christ and the completion of the Canon.
The Bible or Scripture is the inspired Word of God, consisting of 66 books (39 in the OT and 27 in the NT). It is inerrant in its original manuscripts and infallible in its authority. It is the ultimate authority guidebook from God to Man, being necessary and sufficient for every person to know, if they so want to, everything needed for salvation and living a life on Earth for Christ. It is is inerrant in all things it mentions, including science, geology, history, archeology and philosophy, and is to function as a guidebook in those disciplines, even though it is not the textbook for any of these disciplines. As the ultimate authority, whatever it says is to be obeyed. The principle of interpretating it is thus found in itself.
I agree with the statements made by the International Council on Biblical Inerrancy
I believe that God is three persons: Father, Son and Holy Spirit, in one essence, not three modes or manifestations. The three persons are coequal and coeternal in all things, without superiority or subordination among them. In the one essence, God is simple and He is infinite, eternal and unchangeable in all His attributes, perfect in His being.
The three persons are distinct from each other and not interchangeable. The Father is first, unbegotten. The Son is second, eternally begotten of the Father. The Holy Spirit is third, proceeding from the Father and the Son. This definite order is irreversible, and it is reflected in the eternal submission of the Son in the economy of God's plan. In the working of the Trinity, the Father is first, the one who sends. The Son is second, the one sent by the Father from eternity. The Holy Spirit is third, the one sent by the Father and the Son. The economy of God's working glorifies the various persons of the Godhead unto the overall glory of the entire Godhead.
God's plan: Covenant
The Triune God from eternity has a plan which He enacts as the history of the world. The plan is done and conveyed through covenants that God has made both in eternity and in time. In the various covenants that God made with Man, God condescended to Man in those covenants and revealed parts of His great plan to them. The plan of God, the decree of God, works in the history of the world for the glory of God, and the salvation of God's elect.
Jesus Christ is the Son of God, the second person of the Trinity. He is the eternal God, being the Word in Creation. He entered into the world through His incarnation in history as a baby, by being born of the virgin Mary, of the house of David, of the Jews, at the time of the Roman Empire. With this incarnation, he is fully God and fully Man — one person, 2 natures (human and divine), and 2 wills (human and divine), yet the 2 wills work together as one in His one person. He was sinless throughout His entire life, with His mission being to come down to die on the Cross for our sins so that whoever believes in Him would be saved and have eternal life. He was crucified by Pontius Pilate at the instigation of the religious leaders and after 3 days, He rose from the grave and appeared to His 12 disciples, then to other eye-witnesses, before rising to heaven after some time. In the future, Jesus would come back again to judge the entire world.
The Holy Spirit
The Holy Spirit is the third person of the Trinity, fully equal in the Godhead. He is also a personal God and He is given to all believers in Christ during and after Pentecost without distinction at the time of conversion. His purpose is to convict Man of sin, and of righteousness, and the world of judgment. He directs Man to Christ as the Savior of the world and aids believers in their walk and growth in Christ. The Gifts of the Spirit are given to believers to edify the church. The more spectacular knowledge and sign gifts are not super powers but rather special gifts given for the time of kingdom inaguration, and thus they have effectively been withdrawn from use.
God created the world in 6 ordinary days as perceived from the earth, in the order stated in the literal and historical record of Genesis 1. God created a real Adam and real Eve and placed them in the Garden of Eden. The creation was initially very good, without Darwinian evolution — 'nature red in tooth and claw'.
While creation is not covenant, yet Adam from the time of his creation was immediately placed under the Covenant of Works. Adam was commanded to obey God. Disobedience would bring death, and thus obedience would conversely offer eternal life. The covenant having being entered into, Adam could have gained eternal life due to God's promise in the Covenant of Works if he had obeyed.
Adam and Eve, our first parents, sinned against God by rebelling against Him and breaking the Covenant of Works.This original sin resulted in creation being cursed and death coming on all creation, including all mankind, his posterity. Death and suffering entered the entire Creation and Man died spiritually and will someday die physically. Because of Adam's fall, all Man are born sinful, hostile and rebellious towards God and confirm their sinfulness by breaking His law continually. Man is born spiritually dead and hate God, actively, or passively through apathy, with a passion. The Fall affects our entire being, such that we are unable to choose good in God even when given the choice, and unable by our own autonomous reasoning to find God.
God is holy and cannot tolerate sin, therefore Man who is sinful is hated by God. Those who reject God would face His wrath and would be sentenced to hell and the lake of fire, which were initially prepared for Satan and his demons, where there will be eternal torment and eternal separation from God.
God who is Sovereign, chose to save an elect people before the creation of the world, such that He would show His mercy and love on a particular people whom He has chosen, not because of anything they have done, but because of His Sovereign grace. Man who is depraved in his totality will not choose God whatever the circumstances, thus God by His free mercy pour out His saving grace upon this elect, calling and regenerating them and opening their eyes to see their desperate condition before God. In brokenness and repentance over their sins, these people would by faith alone accept Jesus Christ as their Savior, whereby their sins are imputed to Christ and Christ's righteousness imputed to them, and as their Lord, thus living each day in new obedience to God. Thus being justified, they learn to grow in Christ everyday by living by the Holy Spirit in their sanctification.
Although God is the person who saves, evangelism by preaching is necessary
as God is the one who has decreed that this is the method he has ordained to bring His elect to him.
Thus, Christians must evangelize all people and trust God to use us as an instrument to save the elect, whom we do not know,
The sacrament of baptism is the outward sign of the inward sign of regeneration and conversion. As such, every believer should be baptized as soon as possible. Baptism by itself does not confer any salvific benefits apart from faith; it does not therefore mean that those who are not baptized are not saved. There may be saved, non-baptized Christians as there may be unsaved, baptized 'christians'. There is only one baptism in the name of the Father, Son and Holy Spirit, which if valid is not to be repeated.
The Lord's Supper
The Lord's Supper, or the Eucharist, is a sacrament ordained by the Lord, in which only believers are to partake of it and do so after they have examined themselves. It is a remembrance of our Lord's sacrifice on the Cross and waiting for His coming again. Also, it is a sacrifice of praise for His love and grace to us, drawing us out of darkness into His light. In it, we also feed spiritually as Christ, by means of this sacrament, draws us nearer to Himself as we meditate on His atonement and the New Covenant in His blood.
The Church of Jesus Christ is the invisible body of Christ, being made up of regenerate Christians from all denominations, ethnicity and languages. The visible body of Christ is made up of both regenerate and unregenerate people in churches who preach the true Gospel, with those who don't being apostate though they may still be called churches by people.
The true church of Christ has the three marks of the true church: Right preaching of the Word, Right administration of the sacraments, and right administration of discipline. Those who do not exhibit the marks are false churches and believers ought to separate themselves from them.
Within the number of true churches, some churches are more pure and some churches less pure. All true churches are to be recognized as churches and we are to tolerate and carry each other's infirmities. We are to strive to work to promote and preserve the unity, purity and peace of the church of Jesus Christ.
Jesus Christ would come back one day in the future, which only God will know, to bring history to an end, and to judge the living and the dead.
