Married at First Sight expert Pastor Calvin Roberson believes Kate Sisk is the best thing to ever happen to Luke Cuccurullo, and so he's furious about how Luke has been treating her in their marriage on Season 8 of the Lifetime reality series.

During Tuesday night's Married at First Sight: Unfiltered episode hosted by Season 1 MAFS star Jamie Otis, Pastor Cal watched back a clip in which he sat down with Luke and reprimanded him for telling Kate he was "repulsed" and felt "dead inside" following their first real kiss.

"If you can't turn it around, respect this woman, be the man I'm expecting you to be, then you need to get the heck up out of here," Pastor Cal told Luke in the video clip.

Jamie then acknowledged she's never seen Pastor Cal so upset before.

"Yeah, I'm feeling all of that again," Pastor Cal admitted.

Pastor Cal acknowledged he was aware of Luke and Kate's issues before meeting with them in person after their honeymoon -- as shown on the latest episode -- because he receives "constant updates" on each Married at First Sight couple.

"It's a personal thing because we matched these couples. And if we put them together, we expect you to be decent, to treat each other like you're human. I mean, you don't say things to tear each other down," Pastor Cal vented.

Jamie then asked Pastor Cal what really got to him and made him so angry about the situation.

"The thing that got me is [Luke] doesn't value her, and that's what really gets me. Because we know she's value, and he needs to see that. This whole thing is about seeing the worth of the person from the inside out. You know, dead inside? Repulsed? I wanted to say a few other things but they call me 'Pastor Cal,'" he said with a laugh.

"Honestly, you handled that so eloquently, because I think if I was Pastor Cal, I would've said a few choice words that weren't quite," Jamie began.

"Oh my gosh! Well they were going through my head," Pastor Cal confessed. "But I stopped them!"

Jamie then played devil's advocate and questioned Pastor Cal on what might have been going through Luke's head at the time.

"I think he was expressing how he really felt, but maturity says, 'In spite of how I feel, I have this responsibility to this person who is my spouse. And my responsibility is to make sure I protect your feelings. I'm not going to say something to you that is just going to completely destroy you,'" Pastor Cal explained.

When asked how Kate was probably feeling at this point in the process, Pastor Cal said she was "trying to be okay."

"There's no woman that can hear those words and not be hurt, I mean, am I right?" Pastor Cal asked Kate's Married at First Sight co-star Stephanie Sersen, who also appeared on this Unfiltered episode.

"You're right," Stephanie replied.

"I like him," Pastor Cal insisted of Luke, "but in this situation, he's wrong."

Keith Dewar from Married at First Sight's eight season also joined Pastor Cal, Jamie and Stephanie on Unfiltered and offered his two cents on the subject.

"I grew up in a house full of women, so being disrespectful to women is just a no go for me," Keith shared. "It's your wife! You've got to treat her good from jump street."

Stephanie agreed it must have been a really "tough" situation for Kate.

"I can't even imagine what they're going through. But if Kate's not what you're looking for at that moment, she might be what you want a month from now or two months from now," Stephanie reasoned.

"So give it a chance. You can't just expect everything is going to fall into place on Day 1 or Week 1. It's going to be built, and I don't think he's giving that a chance."

And then Pastor Cal pointed out, "I believe [Kate] is the best thing that ever happened to [Luke]."

"If he's not careful," Jamie said, "he might lose the best thing that's ever happened to him by his own actions."

Pastor Cal, however, said he was hopeful Kate and Luke's marriage could still work out.

"You only fail when you quit, so I'm always hopeful. I'm always optimistic about marriage. I believe they can turn things around, but the ball is in his court," Pastor Cal told Jamie.

"If you go to that depth of disrespect, you have a lot of making up to do -- by actions. 'I'm sorry' doesn't do it. There needs to be action, and she deserves better treatment."
