In case a conversation from i-monk comes here, I'm making a spot for it.
Here is something on the church from Luther's sermon (July 12, 1539) on John 3:29.
"The devil is alert and not only rages openly against Christ but also comes to seduce people in the form of the Lord Christ. Therefore let the church beware lest she be deceived by the form of the voice of the Bridegroom, the Lord Christ. For if He will not have the prophets or Moses or John, who really are of God, far less can He endure those who preach something without, or contrary to, the voice of the Bridegroom and who under the semblance of the divine word speak something else. Therefore we should see to it in the church that we preach or hear nothing but the voice of the Bridegroom--not an artificial or imitative voice. For Christ alone is to be He who takes away sin and overcomes death. Therefore believe no one, whether he comes in impressive majesty against Christ or without Christ or for Christ."
I don't want to be rude, but it is of essence to be grounded on Christ and his Word, and not on something else.
