I actually grew up in the Presbyterian Church. I have attended many denominations. My parents go to a Presbyterian Church and I have attended with them. Many of them are saved. They do teach salvation by grace. I have sat in with pastors and leaders and deacons as they have taught Biblical principle. The Trinity of God, The inerrancy of Scripture, etc. Why are we dividing the Church of God. CS Lewis, in Screwtape, describes the Church as not the building or name or the person who sings off-key next to you, but the powerful collection of all who have called on the name of Jesus bearing banners against the Gates of Hell through all time. We need to be bonded in His love, not separated by doctrinal difference. It is essential to understand the Scriptures and to be consistent with them, to know the Power and Grace and Love of God.
