Lutherans are members of the True Church the same as any Christian who is washed in the Blood of Jesus Christ. The True Church is not an earthly denomination. As for our beliefs about. communion they differ greatly from Rome. While we believe what Christ says about His Supper we do not worship the elements. We do not think the bread and wine cease to be bread and wine and are magically transformed into the Body and Blood of Christ rather we receive His Body and Blood in with and under the physical elements. There is no soul and divinity of Christ in the supper. It is not a re sacrifice of Christ and the pastor does not reach into heaven and pull Christ down to the altar. Well i don’t know who wrote this article - but some of it is misleading. I am a life long member of the LCMS with a grandfather and a son that are LCMS pastors so while far from an authoritative source I can speak to what we are taught and believe
Thank God, for the church which the Lord promised to overcome the gates of Hell was not one organic organization outside of which no believers were to be found, but the one true church was and is the body of Christ that the Spirit baptizes every believer into, (1Co. 12:13) and to which He is married, (Eph. 5:25)
For it uniquely only and always consists 100% of true believers, while organic fellowships in which they express their faith inevitably become admixtures of wheat and tares, with Catholicism and liberal Protestantism being mostly the latter.
