@TheFiller It's shown him straight up manhandling demons and other tough foes, and in the arc where Latina gets yelled at by the rogue priest, Dale simply goes to the head of that church branch and flat out told the other priest what was going to happen, and that if it didn't happen that the matter was going to be brought to the top, with the pretty clear inference that 'the top' was absolutely going to rule in his favor no matter what. The amulet he shows the other priest was most likely a symbol of being very highly ranked in his church, or maybe some prestigious war medal.
Though, under all that there is a bit of a feeling of an unspoken promise, that if somehow that church branch escaped legal punishment that Dale would simply erase them in the most painful way he could muster. Dale's power level seems, from what we have seen, to be very high for a human.
