"You're right from your side, I'm right from mine."

that applies JUST fine to stuff like whether cherry pie is better than apple pie, or whether Bob Dylan is better than Eric Bogle...but as to whether wine and wafers change to body & blood, or whether souls really enter embryos, and when, it is not so easy. Wars are fought and lives are affected every day over opinions that can't both be true at the same time....No test will answer any of those questions, and people will believe what they wish to....but I do hope they will someday quit killing each other over their disagreements......
