Megan Phelps-Roper, who looked after social media for the church best known for its slogan "God hates fags", announced her departure in a post on the blogging platform Medium in which she also revealed her younger sister Grace, 19, was also leaving.

In the post, called Head Full of Doubt/Road Full of Promise, the 27-year-old explained how she had become disillusioned with the teaching of Westboro, which is widely considered one of the most detested church groups in America for its "God hates fags" campaign.

Phelps-Roper writes: "We know that we've done and said things that hurt people. Inflicting pain on others wasn't the goal, but it was one of the outcomes. We wish it weren't so, and regret that hurt.

"We know that we dearly love our family. They now consider us betrayers, and we are cut off from their lives, but we know they are well-intentioned. We will never not love them.

"We know that we can't undo our whole lives. We can't even say we'd want to if we could; we are who we are because of all the experiences that brought us to this point. What we can do is try to find a better way to live from here on. That's our focus."

The church doesn't know the exact whereabouts of Megan Phelps-Roper, 27, and Grace Phelps-Roper, 19, spokesman Steve Drain said during an interview. Drain was asked to comment on the news the sisters had left the church.

"Sometimes people come, sometimes people leave," Drain said, noting he arrived at the church 12 years ago. "It happens in the natural course of things."

Drain quoted a verse from 1 John.

"They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us. But they went out, that they might be made manifest that they were not all of us."

When Megan and Grace chose what to do with their lives, they decided they didn't want to serve the God of the Bible, Drain said.

"They wanted to serve themselves," Drain said.

Drain said he has heard the sisters may be in a number of places, including South Dakota and New York City.

"We're not interested in substantiating these things," Drain said. "She (Megan) doesn't want to be here."

As a protester, the older sister has been interviewed a number of times throughout the years.

The church is best known for its zealous anti-homosexual stance and later its nationwide picketing of funerals of soldiers and other military members killed in the war. The picketing started about 20 years ago.

Below is an excerpt from Megan Phelps-Roper's blog post, 'Head Full of Doubt / Road Full of Promise.'

In a city in a state in the center of a country lives a group of people who believe they are the center of the universe; they know Right and Wrong, and they are Right. They work hard and go to school and get married and have kids who they take to church and teach that continually protesting the lives, deaths, and daily activities of The World is the only genuine statement of compassion that a God-loving human can sincerely make. As parents, they are attentive and engaged, and the children learn their lessons well.

This is my framework.

Until very recently, this is what I lived, breathed, studied, believed, preached – loudly, daily, and for nearly 27 years.

I never thought it would change. I never wanted it to.

Then suddenly: it did.

And I left.
