(CNN)-- First it was a Christian pastor in North Carolina who told his congregation on Mother's Day that the way "to get rid of all the lesbians and queers" was to put them behind an electric fence and wait for them to die out.
That video went viral, fetching more than a million views on YouTube.
On Sunday, Pastor Curtis Knapp of Kansas preached that the government should kill homosexuals, in another videotaped sermon that drew lots of online attention.
"They won't, but they should," Knapp said, according to a recording of his sermon posted online.
Since that sermon, another church video with harsh words for gays has caught fire online. This one shows a young boy singing an anti-gay song while the congregation cheers him on in what appears to be a church in Indiana.
"I know the Bible’s right, somebody’s wrong,” the boy sings near the pulpit of a church. “Ain't no homos gonna make it to heaven."
As the boy repeats the line “Ain't no homos gonna make it to heaven," congregants from the pews rise and cheer.
The video, which was anonymously posted online and has received more than 300,000 views on YouTube, appears to show a service at the Apostolic Truth Tabernacle Church in Greensburg, Indiana.
Calls to the church this week went to voicemail, with an automatic message saying the mailbox is full. But a message posted on the church’s website on Wednesday appears to address the controversy, offering no apology for the video.
“The Pastor and members of Apostolic Truth Tabernacle do not condone, teach, or practice hate of any person for any reason. We believe and hope that every person can find true Bible salvation and the mercy and grace of God in their lives,” the statement says.
“We are a strong advocate of the family unit according to the teachings and precepts found in the Holy Bible,” said the statement, which did not explicitly refer to the video or mention homosexuality. “We believe the Holy Bible is the Divinely-inspired Word of God and we will continue to uphold and preach that which is found in scripture.”
The viral videos have drawn criticism from gay and lesbian groups and their allies.
Charles Worley’s sermon at Providence Road Baptist Church in Maiden, North Carolina, sparked a protest that drew more than 1,500 people last weekend.
In Kansas, Knapp's voicemail at the New Hope Baptist Church in Seneca was filled with messages saying "things you don't want your kids to hear," he told CNN affiliate KTKA.
An official with the Kansas-Nebraska Convention of Southern Baptists issued a statement to CNN on Thursday saying that Knapp’s church had left the Southern Baptist fold in 2010.
“Obviously, he has taken a radical and unbiblical stand in regards to homosexuality,” said Tim Boyd, communications director for the convention.
“We look at homosexuals as we look at all sinners,” his statement said. “God loves them. Christ died for them. The Gospel calls them to repentance and salvation. Therefore, we as Christ-followers should hate the sin and love the sinner.”
But Knapp is not backing away from his comments.
"We punish pedophilia. We punish incest. We punish polygamy and various things. It's only homosexuality that is lifted out as an exemption," he said.
He cited the Biblical verse Leviticus 20:13: "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act. They shall surely be put to death."
But he said gay people had nothing to worry about from the government or from him.
"I don't believe I should lay a finger against them," said Knapp, of New Hope Baptist Church in Seneca, Kansas. "My hope is for their salvation, not for their death."
Preaching against homosexuality the same day, another pastor appeared to wrestle with how conservative Christians should respond to proposals that people should literally mete out biblical punishments.
"What about this guy down in North Carolina said build a big prison, a big fence and put them all in there and let them die out?" Dennis Leatherman asked in a sermon at the Mountain Lake Independent Baptist Church in Maryland.
"Listen, I don't know that fellow. As far as I can tell, he seems like a decent guy, but he is dead wrong on that. That is not the scriptural response," Leatherman said in his sermon "Homosexuality & the Bible," according to a cached version of the transcript posted online.
The audio of the sermon does not appear on his church's website.
In the sermon, he floats the idea of killing homosexuals, whom he refers to as sodomites, then backs away from it.
"There is a danger of reacting in the flesh, of responding not in a scriptural, spiritual way, but in a fleshly way. Kill them all. Right? I will be very honest with you. My flesh kind of likes that idea," Leatherman said.
"But it grieves the Holy Spirit. It violates Scripture. It is wrong," he added immediately.
The Southern Baptist Convention distanced itself from Worley's remarks.
The nation's largest Baptist group said Providence Road Baptist in Maiden is not affiliated with its 16 million-member denomination and condemned the comments.
But the influential head of the giant movement's seminary does argue that homosexuality "is the most pressing moral question of our times."
In a comment piece for the Belief Blog in the wake of Worley's sermon, R. Albert Mohler Jr. dismissed critics who say conservative Christians focus on homosexuality while ignoring other things the Bible prohibits.
He contends that laws about keeping kosher, for example, do not apply to Christians, while commandments about homosexuality do.
"When it comes to homosexuality, the Bible's teaching is consistent, pervasive, uniform and set within a larger context of law and Gospel," he wrote.
"Christians who are seriously committed to the authority of the Bible have no choice but to affirm all that the Bible teaches, including its condemnation of homosexuality," he said.
A member of Worley's 300-member church defended him in an interview with CNN's Anderson Cooper.
"Of course he would never want that to be done," Stacey Pritchard said of the proposal to put homosexuals behind a fence and leave them there to die out. "But I agree with what the sermon was and what it was about."
