Does Christian Unity Allow for Variety ?

Unity in the Christian congregation is vital.
Disunity in doctrinal belief would rise to fierce disputes,
dissension , and even enmity.
{ Acts 23:6-10}

The Bible says that " God is a God , not of disorder, but of peace."
{ 1 Corinthians 14:33 }

Are theses words and similar Bible passages encourageing strict uniformity among Christians in every respect ?
{ John 17:20-23 } { Galatians 3:28 }

Does true Christianity as described in the Bible encourage variety when it comes to individual personalities ?

Are all Christians expected to fit into some sort of rigid mold ?
