Ambrose was a really important guy a long time ago. He was a bishop, which means he was kinda like a boss of a bunch of churches. He lived in a place called Milan and he was super smart and wrote a lot of important stuff. Ambrose was also really good at speaking and people loved to hear him talk.
One time, there was a lady who was really mean to some people, but Ambrose didn't like it. So he made her leave the church and stay away for a while. She eventually said sorry and he let her come back.
Overall, Ambrose was a really cool guy who did a lot of important things and people looked up to him.
