The practice of painting Episcopal Church doors red goes back to the Middle Ages. Typically, the north, south and east doors of the church were painted red. The red color symbolizes the blood of Christ. The three doors signify making the sign of the cross, as the doors represent the Father, Son and Holy Spirit.
Of course there are other explanations for why Episcopal Church doors are red. Most are a variation of the explanation above. Some say the red signifies the blood of Christ which is our entry into salvation. They also remind us of the blood of the martyrs, the seeds of the church.
Some say the red doors are a reminder of the Passover as explained in the Bible in Exodus 12. The Lord directed the Jews to paint the door frames of their homes to protect their children.
Still, there are simpler explanations for why the Episcopal Church doors are painted red. Some say it is a sign the mortgage is paid off. Still others state the decision was made to make the church easily recognized and visible as an Episcopal Church. It must be stated, however, some Episcopal Church doors differ from the red color scheme. Peace Episcopal doesn't have a red door as we are sharing space with the historic Shiloh Church in Rockport, Indiana.
The fact that some Episcopal churches choose to paint their door a color other than red is actually very symbolic of the Episcopal Church. The Episcopal Church is a welcoming group of believers and encourages people from all walks of life to come together in faith to pray and worship the Risen Lord.
