I'm curious as to what exactly he needs to apologize for? You say fraudulent behaviour, so he's been fraudulently saying his marriage was perfect? Or are you saying because of this area of his life was falling apart, he was fraudulent in all he did? See I don't know how the board found out, nor do I know how far the relationship went, but if we all follow these rules, let me appologize as well, I had a doozie with my wife a few weeks ago. Then three days ago, I have to appologize for this as well, I didn't help with the house cleaning. I also need to repent, I thought more about going for a bike ride than I did about what was happening with my children. And I'm sorry I didn't help clean the house again today, but I did hurt my foot.
But thinking about it, I don't recall reading Peter's open appology to the church when he cursed Jesus. As a matter of fact, I don't read very many appologies. Where did Paul appologize to Stephen's family?
And what exactly will an appology do? I am one who doesn't believe divorce to always be sin, so how am I to tell if this one was? The only thing I could see needing an appology is if he told people his marriage was perfect and it was a lie. I don't recall him talking about his marriage though, although truth be told, I didn't listen to him much.
Personally I'm glad God uses people who fail, it gives me hope.
