Prayer Foundation. Retrieved 2007-10-18. "The flag's most conspicuous symbol is the Christian cross, the most universal symbol for Christianity. The red color represents the blood of Christ and brings to mind his crucifixion. Christians believe that Jesus Christ's death and resurrection is the means God uses to save believers from their sins. The cross and blood have been used since earliest Christianity to symbolize salvation through Jesus; in the words of the Apostle Paul, "And having made peace through the blood of his cross, by him to reconcile all things unto himself;" — Colossians 1:20. The white field draws on symbolism throughout the Bible equating white clothes with purity and forgiveness. People who have been "washed white as snow" in the Bible have been cleansed from their sins (Isaiah 1:18; Psalm 51:2). In conventional vexillology (the study of flags, their history and symbolism), a white flag is linked to surrender, a reference to the Biblical description Jesus' non-violence and surrender to God's will. The symbolism behind the blue canton has been interpreted to represent Heaven, truth, or the Christian ritual of Baptism in water."</ref> ขนาดของธงยังไม่มีข้อกำหนดขนาดอย่างเป็นทางการ
