Rather, any church that claims that it particularly is the "true church" is cultic, and one that believes regeneration occurs thru a ritual even for souls who cannot fulfill the stated requirement for that (infants), which is wholehearted penitent heart-purifying faith, (Acts 2:38; 8:36,37; 10:43; 15:7-9) is an seriously aberrant church.
And as for "historic liturgy," you mean,
How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying. If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret. But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. Let the prophets speak two or three, and let the other judge. If any thing be revealed to another that sitteth by, let the first hold his peace. For ye may all prophesy one by one, that all may learn, and all may be comforted. (1 Corinthians 14:26-31)
And do you think "not discerning the body" in 1 Cor. 11 refers to what is being consumed, vs. the body of Christ? See here
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
