In his simple explanation of the Apostles' Creed, Dr. J.I. Packer writes,
"When [the creed] called God "maker of heaven and earth," it parted company with Hinduism and Eastern faiths generally; now, by calling Jesus Christ God's only Son, [our creed] parts company with Judaism and Islam and stands quite alone. This claim for Jesus is both the touchstone of Christianity and the ingredient that makes it unique."
It's helpful for us to remember this truth as the touchstone of our faith and the very thing that makes Christianity such a vital religion with a message of truth and life for all who will listen!
