I will say to our shame that we were too weak to do that

"I shamefully admit that we were not bold enough to treat you like that." or "I am not ashamed to say that we had the power to harm you, but we treated you well"

Yet if anyone is bold ... I too will be bold

"Whatever anyone boasts about ... I will dare to boast about it also." Paul's boldness here is the boldness to boast.
