Baptism of fire in Context
“It was my first day on the slopes, and in my naivety I had tackled Avoriaz’s famous Boulevard des Skieurs after one three-hour lesson, before I could even really turn. At 36, this was a baptism of fire.” — Jaymi McCann, The Week, 23 Jan. 2026.
Did You Know?
The military sense of baptism of fire can be found in, among other texts, a 1907 history of a Massachusetts regiment in the Civil War: “That night we camped sixteen miles from Baton Rouge where we remained until the 21st, on which day we received our baptism of fire.” Users of that sense, referring to a soldier’s first exposure to enemy fire, as well those employing the more general sense of an especially difficult initiation, both allude (knowingly or unknowingly) to a Biblical passage: “I baptize you with water for repentance, but he who is coming after me . . . will baptize you with the Holy Spirit and with fire” (Matthew 3:11, RSV). The use of baptism of fire to refer to such a spiritual baptism dates to at least the early 1600s. Non-biblical, metaphorical use for any introductory or initial experience that is a severe ordeal arose in the mid-1850s.
