The basics
We believe that Jesus Christ is the way, the truth, and the life - see John 14:6. In other words, we believe that Jesus is the way for us to be reconciled to God, that He is the embodiment of God's truth, and that being united to Him by faith is the way God's life is born in us. In short, that life - real life - is all about knowing Him, as Jesus himself prayed in John 17:3.

More formally
As a Christian church, like all Christians we believe what's affirmed in the creeds of early Christianity, such as the Apostles' Creed and the Nicene Creed.
As a Presbyterian church our elders and ministers hold to a 17th century document called the Westminster Confession of Faith, read in the light of a 1901 document called the Declaratory Statement.
