"All Saints" is a reference to the fact that Scripture calls all who put their trust in Christ "saints" which means "holy ones" or "those who are set apart". We, in this church and in our worship, are being joined by God to "all the saints" throughout history in the worship and service of God. Paul describes this as stones being joined together into a holy temple (Ephesians 2:19-22).
Our logo is called a "chi rho". The chi rho is an ancient symbol of the church that consists of the first two letters of the Greek word for Christ. We wanted our logo to connect us to the rest of the Christian church in history rather than set us apart from it. Also, the person and work of Jesus Christ - his life, death, and resurrection - are central to all human history as the ultimate act of deliverance.
