'Married at First Sight' Spoilers 2018: What Happens to Dave and Amber?

Mia Bally and Tristan Thompson aren't the only Married at First Sight couple from Season 7 to hit a hurdle. Amber Martorana and Dave Flaherty clashed over religion, as shown in an exclusive video shared by Lifetime with Newsweek.

"As far as religion goes, I wasn't really raised in a religious household so it's not something that was really part of my life," Martorana tells the Lifetime cameras. "It's just hard for me personally to just choose one religion and say that this is the only way to God because I feel like they're all saying the same thing."

"I just like spiritual aspects," she tells her new husband. "Like I like believing in a higher power or things coming together. Like I told you in my vows, there was a reason I kept going with this process. It's OK if I'm with someone who is religious as long as you don't expect me to change."

While Flaherty didn't want Martorana to convert, he didn't sense she was open-minded either. "I don't expect you to change, but I also think that you—from our brief conversation about it before this—are pretty opposed," he said.

That's when Martorana put her real feelings about people with faith out there. "I just feel like most people who are religious are hypocritical and they like to judge people because they think it's like their shield to judge," she said.

Flaherty "respectfully" disagreed. "In the most respectful way possible I think you're being a little judgmental," he said. "I don't think it's as black and white and you think it is."

"Married at First Sight" stars Amber Martorana (pictured above) and Dave Flaherty arguably hit their first roadblock as a couple when the subject of religion came up. Lifetime

Despite having different beliefs on such an important topic, Flaherty seemed hopeful. "Religiously, Amber and I don't line up. I wouldn't characterize myself as very religious, but I am religious and I do have a strong faith and it's something that's important to me so we're going to have to figure it out," he said. "Maybe some of her beliefs about religion can change."

Martorana, however, didn't back down. "There's just no guarantee that I'm going to feel the same way that you do," she said. "I have no idea how we work through this."

In his final message of the sneak peek clip, Flaherty didn't seem as confident anymore. "When it comes to religion, I think it was a little bit more of a bigger deal than I initially realized," he said.

Married at First Sight airs on Tuesdays at 9 p.m. ET on Lifetime.
