Are you being sarcastic or serious?
It's alittle hard to tell sometimes over the internet.
It is never a good idea to mock the beliefs of others. No. I was serious with my comment regarding the veracity of Christian theology. I do sincerely believe that human beings are created as souls in heaven in a condition of innocence and from there embark upon a series of lifetimes in human bodies, each one a different personality and embedded in a different culture so that all the lessons that the earth setting can teach can be learned. To this end, good bad, fat thin, ugly good looking, rich or poor, black or yellow or red or whatever or white.... All the lessons that humanity has to offer are included in these "classrooms".
The reason that Christianity does not teach this is because first it is not necessary to know in order to progress. It is much better that people are taught about sin and punishment so they will pay attention and stay on the correct path in life. Teaching the other has, in centuries past, had the effect of people getting the idea that they could play around while here and have a good time because they could make up for it later. It is easy to see the truthfulness of this. It was a common practice in a time of ancient China that people would incur a debt promising to repay in the next life. See why it is kept secret? So the Christian teaching is the better approach for this time in the experience of humanity. But there is a problem here too.
The newest Christian twist to ancient Christianity is the business regarding being born again. It's OK that people participate in this ceremonial because they otherwise might not be able to have some clear turning point in their lives. Does it matter if it is only a certain sub set of protestant churches that teach this? Not in the slightest. Fact is that the various orthodox and Roman church has had established sacraments (as they call them) which addressed the very same ideas. Now sometimes I hear that one is only a real Christian from the time when, as an adult, they "give their lives to Jesus, Lord and Savior". I have been told that Catholics, for instance, are not real Christians because they do not do this. This, is an example of the "wrongness" that I think of when I say that "all religions are wrong". Wrong because it constitutes separative teaching rather than inclusive and loving.
The Word of God is modified by the emotional workings of the smaller mind of man. It always has been and until we approach perfection it will continue to be thus. If this were not true then all Christians would refuse to use any but the most original version of the Bible which came into being when Constintine converted to Christianity after winning a major victory, brought together the leading authorities of the day, decided what the content of the Bible would be and finally ordered 50 copies as a new beginning. This was the first codified "benchmark" work that we call the Bible. Most other religions would never think of changing their scriptures but Christians have done so many times over the years.
Note: It is of interest to know that when Islam claims that the Bible is "corrupted" they are saying that they know about all the times that Holy Book was edited. They ask, "who dares to change the Word of God"? They do not understand how this could happen. The Quran today is exactly the same as the very first one and will never be changed. The Muslims are in agreement with most of what Christianity teaches but this is one great exception. Like it or not this is a true bit of our history. We seem to forget our own flaws sometimes. Pity.
So are the American believers incorrect in their practice of Christianity. No. All that really matters from the viewpoint of the Father is that we all endeavour to follow the teachings of Jesus during His ministry. Those were exemplified in the Sermon on the Mount. The emphases which is placed today on belief and obedience is best when they are understood that cooperation with God is the highest and best path a man can take.
I believe that there will be a time when all religions, especially the three great Abrahamic, Judaism, Christianity and Islam, will reconcile and join hands in worship of God. What a happy day this will be for the whole world. If we can manage this we will have proven to God that we have become adults in spirit. Jesus is about to return and when He does He will teach this idea I believe. Imagine the power possible when the Old Testament, the New Testament and the Quran are combined. Think of those future possibilities and then remember what we have in the world today. Religious strife, anger, intolerance, insistence that only one way is correct etc...etc. We need to stop being fools and listen to God for a change.
My beliefs are the result of a life time of study...
Assalamu Alikum....God Bless us all....Shalom
Sorry for the length here. That is one thing I can't seem to help.
