God created us to love him and each other, but we fall short of this and instead turn inwards, making self-satisfaction our goal and placing our trust in anyone and anything but God. Jesus Christ came into the world to take awaythe consequence of this way of life and restore us to the only one who can ultimately satisfy. In him, we see real love, service, compassion, and the ability to heal the human condition by making us right with God.
Everything we believe flows from the Bible because we are convicted of its inspiration, truth, relevance to everyday life and authority as God’s written word (see 2 Timothy 3:16-17)
Jesus was a real person in history, he is the sinless Son of God. First century political and religious leaders put him to death because of his "radical" claims to be God in the flesh, the Divine King promised in Scripture (Messiah), and his message of salvation through faith exclusively in him alone (1 Timothy 2:5-6).
Jesus died for his children because he loves us and because we need a perfect Saviour to take God's just punishment for us (John 6:37-39). Jesus' died and was buried, but on the third day he physically rose from his grave and appeared to numerous eyewitnesses (1 Corinthians 15:3-4), and whose lives were changed forever as a result. Many went on to die horrible deaths defending the claim that Jesus is who he says he is. Because of Jesus' death and resurrection, when we confess our sin and put our faith in him, we are saved from final judgment and brought into union with his eternal life (John 6:40).
The Holy Spirit is the third member of the Divine Trinity (Father, Son, and Holy Spirit—Three in One and One in Three); he draws us to Christ; gives us saving faith to believe the good news; and strengthens us to live holy (albeit imperfect) lives of obedience to Jesus (Romans 8:5-11). Being a follower of Christ requires personal and often costly sacrifices (Luke 14:25-35), but the Holy Spirit gives us comfort and joy, even in the midst of life's worst trials.
The Church, the Body of Christ, is a collection of saved sinners across space and time. We are committed to loving and caring for one another. Most importantly, we cultivate relationships to help each other grow in grace and love for our Lord Jesus Christ (Romans 12:9-21). Prayer is a powerful gift from God through which we receive grace and forgiveness (Philippians 4:6).
The Church is commanded to reach out to the world with an indiscriminate call to faith in Jesus Christ (Romans 1:16) and generous service and compassion. We are responsible to influence the world for the good - living the good news of the gospel (Matthew 28:19). Jesus will come again; and when he does, he will renew the cosmos and clothe his people in bodies fit to live on a renewed earth forever. Those without faith in Jesus will receive face God's judgement without the saving intercession from Jesus (Matthew 25:31-46).
As Presbyterians, we love the Bible and our beliefs are all contained and authorised by God's word. As a good summary, the Westminster Confession of Faith (WCF), which is a summary of church teachings developed in the early 17th century by some of the greatest theological minds at the time. It has certainly stood the test of time and continues to be a useful tool to our churches today. Here is a link to the Presbyterian Church of Australia's document - The WCF for Australians in modern language. Our Minister and Elders are always delighted to help answer questions. As the old joke goes - "Theology is a verb..." which is a good way of saying that using your beliefs in everyday life is far better than just knowing them.
