Marriage Exception Matthew 19:9 - Porneia

Does the exception clause in Matt 19:9 allow for divorce from a Christian marriage and a subsequent remarriage ?  

No.

I was researching Catholic understanding of 'porneia' and found this website for the first time!
I am glad his answer to the question was NO, also. 

We seldom here this stated in today's world!
