Maybe you've already noticed: unlike most churches, we don't have a main entrance, but rather seven evenly spaced doors. This is intended to symbolize that no matter where people come to the Frauenkirche from, all people are equal before God.
Based on Paul's letter to the Galatians: "There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus."
At the same time, the missionary command from the Gospel of Matthew was cast into the architecture here: "Therefore go and teach all nations: baptize them in the name of the Father and of the Son and of the Holy Spirit and teach them to observe everything I have commanded you."
The members of the church should spread out all over the world, in all directions, and share the gospel that they have received here with everyone they meet.
