E. Stanley Jones was a 20th century Evangelist who devoted his life to following Christ and spreading the Gospel. He spent many years in India and wrote The Christ of the Indian Road It is full of powerful insights into the Gospel and the best ways to spread the Gospel.
In the chapter What or Whom? he points out that when Christians start discussing What they believe conflict arises and causes dissension. When Christians discuss Whom they believe, Jesus, they are brought together. The Church divided once over Whom to believe in. The Unitarians split off, and that is the right thing because they no longer believe Jesus is central. The Church is headed in the right direction if it makes Jesus Christ central and doesn’t worry overmuch about all else.
