HN,
If scripture is the word of God and Christ’s promises found in scripture can be relied on, Luther’s doctrines must be false. Here is why.
Jesus promised that He would send the Holy Spirit to lead His Church into ALL truth, and to be with His Church until the end of time. He made promises guaranteeing the doctrines of His Church, binding in heaven what His apostles bind on earth. He founded His Church on men, not scripture, according to scripture.
If we are to take Him at His word then we can conclude that the things the Church believed in the year 100 were true. The same is true for the year 500, 1000, 1500, 2000.
One test of any doctrine would be whether or not it agrees with the truths of faith the Church has always taught. For example only, if some group or sect comes along at some late date and says they refuse to believe that babies should be baptized, and there is historical evidence from the very beginning that the Church baptized babies, the novel doctrine must be false if Christ’s promises to His Church as found in scripture are true.
The Holy Spirit is either leading us into all truth for all time, past, present and future, or He is not. According to Christ’s promises the Church can not believe or teach error, ever. If Joseph Smith’s claims are true, that he have a vision of an angel who told him no Christian group’s doctrines are true, the Christ’s promises are false.
If history shows that the Church has always prayed for her beloved dead and someone says this is nonsense that person is wrong, or Christ’s promises are false. Truth can not change. The oldest historically known rote prayer is from the year 50. Mary was still alive. It is a prayer to Saint Joseph. This is history not theology. If someone says it is wrong or useless to pray to the saints and the Church has always done this, the novel doctrine or Christ’s promise is false.
The same is true of morals. If the Church has always taught that it is sinful for people to engage in homosexual behavior and it is not sinful as some now claim to have discovered, and they are correct, then the Church was wrong since the begining and Christ’s promises are false, because the Church taught and believed error. This is very serious matter. It would mean the Church has heaped guilt and shame on people unjustly for two thousand years.
Anyone who opposes the constant practice of faith the Church has always upheld, under the claimed authority of their personal reading of scripture, must either be wrong, or Christ’s promises to us about leading into all truth for all time are false.
If Luther taught what contradicted faith and practice that was believed from the beginning based on his personal understanding of scripture, he is wrong.
If Luther is right and the Church is wrong this would also mean that no doctrine can be relied upon. It becomes impossible to know that what you believe is true if it can suddendly be declared by someone as an error based on some new understanding of scripture. This is what unleashed denominationalism on us, which is a never ending adjusting and changing and fixing doctrines according to someone’s new opinion.
