Early Christians used shells to pour water on the heads of those baptized.
Until the Middle Ages, most baptisms were performed naked.
In Western Europe, affusion baptism—where water is poured on the head—became popular between the 12th and 14th century.
In the 16th century, Martin Luther cast his vote for infant baptism in his Large Catechism, saying that it was God-pleasing because it signaled rebirth by the Holy Spirit.
Some American churches in the South use Plexiglas pools in the sanctuary, similar to dunking tanks. A person sits on a platform, which is released so that the person is immersed in water.
At the Jordan River, near the spot where Jesus was baptized, submersion baptisms are performed. A person walks into the river and is dunked briefly underwater.
And in Norway … a baby was baptized in 2009 with lemon cola instead of water, after the church’s water pipes had frozen
Suffice of to say baptism hasn’t always been the same. From the days of Jewish ritual cleansing, to the baptism of Jesus, to dunk tanks and lemon soda. One thing is true, no matter how it is done, baptism is a promise. A promise that we will reject sin, follow our savior and believe in our god above all else.
It is also a promise made by god that we are marked, protected, purified and loved as his children. We may only be baptized once, but it is a promise that we renew each and every day, to follow the teachings of Christ. And a promise full filled, in God’s grace, each day when we fall short of our potential.
