We conclude, therefore, that a Christian lives not in himself, but in Christ and in his neighbor. Otherwise he is not a Christian. He lives in Christ through faith, in his neighbor through love. By faith he is caught up beyond himself into God. By love he descends beneath himself into his neighbor.
Martin LutherAlso when it is a case of only upholding some spiritual tenet, such as infant baptism, original sin, and unnecessary separation, then . . . we conclude that . . . the stubborn sectaries must be put to death.
Martin Luther
