Reformed: that's not the final destination of the church.
The church is ALWAYS to be reformed.
Note that the church is not the agent of reform; the Word of God is the agent of reform.
Do not misunderstand that the church reforms itself; it's God that reforms the church. Therefore, to translate semper reformanda "always reforming" is misleading.
secundum verbi deo: According to God's Word the church is always to be reformed.
