The word “sacrament†is not the correct term to use here – the word “ordinance†is. Roman Catholicism, Eastern Orthodoxy, and a few of the Protestant denominations use the term sacrament to refer to a sign/rite which results in God's grace being conveyed to the individual. Typically, there are seven sacraments in these denominations. They are baptism, confirmation, holy communion, confession, marriage, holy orders, and the anointing of the sick. However, we don’t believe that at all. The Bible tells us that grace is not given through outward symbols and no ritual is “necessary for salvation.†Grace is free. Most Protestants see ordinances as symbolic reenactments of the gospel that Christ lived, died, was raised from the dead, ascended to heaven, and will someday return. Rather than requirements for salvation, ordinances are visual aids to help us better understand and appreciate what Jesus Christ accomplished for us in His redemptive work. Regarding foot washing. This was something Jesus did as a one-time event in that context. In John Chapter 13, the washing of feet was a custom and tradition of that time. Just as greeting one another with a “holy kiss†was in Romans 16:16, as Paul was greeted by those who loved him (Acts 20:37). 1 Corinthians 11:5,6 describes a woman having her head covered in public, as it was the custom to do so. If her head was not covered, she was considered a prostitute. Some of these customs are still practiced in a few countries today. In America, the hand shake is a custom replacing the “holy kiss†of the Middle-East.
