Well, more of the Bible is being denied and questioned as authentic as time goes on so it's not just your father. I personally believe it's all inerrant and have found no strong evidence to prove otherwise. I would be interested to know what parts he thinks are stories,surely he can't think Genesis can be a story, because if there was no Adam,there was no fall,there is no inherited sin.....which leads to total depravity,which is foundational in Reformed. Not asking you to speak for your Dad hehe. And it's nice that you found a church that you like and a community that's right for you. I agree religious talks should be handled cautiously.
