Of course it is.  It's the epic story that was true before His days with us, while He was with us, and even now.

Note how when the rich man went away sad..separating himself..Jesus didn't say.."well you don't have to give up everthing..I was only acting!"

Nor when He spoke so jarringly about the Eucharist...when others fell away...He didn't chase after them.

These are examples of division and we have them and many more today.

Jesus doesn't want division...He wants unity with Him in the Truth...but He won't do damage to our free will either. 

Notice His point on divorce.
