Baptism and Communion are two physical illustrations God put in place to teach us spiritual truth. We, being physical, tend to obsess over the physical details and bash each other over the head with them and completely miss the spiritual truth being taught.
Church History shows Christians literally killing each other over whether people should be dunked in water or sprinkled, whether the water you’re dunked in should be still or moving, is the bread and cup actually the literal body and blood of Christ, and various other physical details.
While some in the church fixate on the physical details, others see a spiritual point and dismiss the physical aspect entirely.
I know people who refuse to take communion or be baptized because they don’t want to rely on a physical work. Others ignore them because they are spiritually enlightened enough to not need such physical reminders. “We think about Jesus every day without that stuff.” Congrats.
People enjoy extremes. One group fixates on the physical rule-keeping; the other group fixates on the spiritual part and throws out the physical.
God knows our frame. He knows we’re physical. But as true believers in Christ who possess the Holy Spirit and have been born again, we are spiritual creations. We are a blend of physical and spiritual.
True believers should be the one group who can grasp both physical and spiritual aspects of communion and baptism. We don’t have to throw them out, nor do we need to fixate on physical details. We can grasp the physical and the spiritual parts because we are both parts!
