This is debate #1 from a two-night debate...
Church of Christ Debate: Is Baptism Absolutely Necessary for Salvation? Patrick Donahue from the Church of Christ affirms that salvation is impossible without water baptism, no matter the circumstance. Traever Guingrich from Grace Chapel Reformed Baptist Church denies its absolute necessity & says it is something people do because they ARE saved, not to GET saved.
