text: No.  Christians are also changing their understanding of God, nature, humankind, the relationship with God, what He wants of us, how we honor Him.  Or, as Pope Francis recently said:  "Doctrine cannot be preserved without allowing it to develop, nor can it be tied to an interpretation that is rigid and immutable without demeaning the working of the Holy Spirit."
  
  Who are you to decide who is or who is not a Christian or who is or who is not Catholic?  A fallible human like any other.  Leave the judging to God.
