Yep. As someone who used to be seriously Catholic, there are no quick "gotchas" within religious rules that outsiders can come up with. This particular argument, it's quite common, I can use my old Christian mindset to generate at least three separate rationalisations against it. There are so many thought-stoppers and complex intellectual justifications involved in serious religious belief because if you set the human mind to proving something any way possible, you'll spring an infinite fountain of bullshit. Don't get into the weeds of why Christians believe what they do, because the ones who care about scripture know more than you and the ones who don't won't be swayed.
