It is true there are different understandings and interpretations within the Christian church, Out. What is more it is also true is that Church unity should be sought, according to the Bible,
"5 Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus:
6 That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
7 Wherefore receive ye one another, as Christ also received us to the glory of God." (Romans 15:5-7King James Version KJV)
Added to this, according to Christian belief, we are also called to remember our own limitations and acting in love, towards one another, is seen as the most important priority.
"11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
13 And now abideth faith, hope, charity, these three; but the greatest of these is charity." (1 Corinthians 13:11-13King James Version KJV)
So, whilst not straightforward, Christian belief requires to us to accept we will not know everything there is to know in this life, regarding God and what is good, but to seek at all times to act in love towards one another. I like this.
