Roman Catholics PRAY TO saints.... THAT is believing in multiple gods to some, yet I would not say they are not Christians.
Look, I am not Mormon, I disagree with a huge portion of their beliefs. Here is the question...
WHAT IS A CHRISTIAN?
This question assumes that there is one and only one correct definition of the term “Christian.” However, depending upon your understanding of the nature of truth, many definitions may be “true” to various groups:
To conservative Protestants, a Christian is often defined according to their salvation status. Their definition is “true” to them, because it agrees with some of their foundational beliefs: that the Bible is inerrant, that salvation is by grace, and that one must be “born-again” to be saved and avoid eternal punishment in Hell.
To Roman Catholics, a Christian is often defined according to their baptism status. Their definition is “true” to them, because it agrees with their fundamental beliefs about the nature of sacrements, their understanding of the Bible, the declarations of many Church Councils, the statements of many popes, and their church’s tradition.
To many in the very early Christian movement, a Christian was defined as a person who was baptized and proclaimed “Jesus is Lord.” Their definition was “true” to them because it agreed with their understanding of their religious belief at a time when the Christian Scriptures (New Testament) had not yet been written and assembled.
And so on, with other faith groups.
Each group has their own definition of “Christian” which agrees with their own beliefs about the nature of Jesus, God, church tradition, written text, evolved theology, the cultures in which they are implanted, etc. There appears to be no way to compromise on a single definition that is acceptable to all. One apparently cannot call on a higher power to resolve the problem, because there seems to be no way to assess the will of God on such matters. If there were such a method, then different definitions would have been harmonized centuries ago. People would simply have prayed to God and asked Him to define what a Christian is. Then, a consensus would exist today on the true meaning of the word “Christian.”
There is no consensus on what the “correct” definition of “Christian” is. There is only a near consensus within individual faith groups. Therefore questions like “Are you a Christian?” or “How many Christians are there in the U.S.” are only meaningful:
Within a single denomination, or among a group of similarly-minded denominations.
The point is that all Christian churches do agree on one thing, that Mormonism is not a Christian religion.
You seem to keep avoiding that unanimity.
Your understanding of Christianity and it's practicionsers seems some what limited. Perhaps more study in in order to understand the boundaries of what is Christians and what is cult would be in order. For example I do not know where you get the idea that Lutheran baptism is not accepted by Baptist. Perhaps a local Church made such a request of a new member but I also know Lutherans, as well as Catholics and others who have not been required to do so by the Baptist Church. Further more from personal experience I know the Methodist Baptism is accepted by the Greek Orthodox Church.
It is not your fault, proper Christian instruction in this liberal age is hard to come by regardless of the denomination, but there are boundaries that all Catholic, mainline Protestant and Orthodox agree with starting with the Trinity.
There is UNITY in knowing what a FALSE PROPHET is; and Joseph Smith, by his own writings, fits the bill perfectly.
