A real scientist is a passionate being who loves his theory and will fight for it because he believes that it’s true. The risk is that he is wrong. This risk is mitigated by the other scientist who is passionately committed to his own theory and will engage in intellectual combat to advance and defend it. Both are scientists. It’s in the friction between them that the truth emerges and advances occur.
A real scientist applies the scientific method of inquiry, and draws conclusions. You’re describing a theologian.
