Contemporary American Christian terrorism can be motivated by a violent desire to implement a Reconstructionist or Dominionist ideology.[98] Dominion Theology insists that Christians are called by God to (re)build society on Christian values to subjugate the earth and establish dominion over all things, as a pre-requisite for the second coming of Christ.[99] Political violence motivated by dominion theology is a violent extension of the desire to impose a select version of Christianity on other Christians, as well as on non-Christians.

After 1981, members of groups such as the Army of God began attacking abortion clinics and doctors across the United States.[100][101][102] A number of terrorist attacks were attributed by Bruce Hoffman to individuals and groups with ties to the Christian Identity and Christian Patriot movements, including the Lambs of Christ.[103] A group called Concerned Christians was deported from Israel on suspicion of planning to attack holy sites in Jerusalem at the end of 1999; they believed that their deaths would "lead them to heaven".[104][105]

Eric Robert Rudolph carried out the Centennial Olympic Park bombing in 1996, as well as subsequent attacks on an abortion clinic and a lesbian nightclub. Michael Barkun, a professor at Syracuse University, considers Rudolph to likely fit the definition of a Christian terrorist. James A. Aho, a professor at Idaho State University, argues that religious considerations inspired Rudolph only in part.[106]

Terrorism scholar Aref M. Al-Khattar has listed The Covenant, The Sword, and the Arm of the Lord (CSA), Defensive Action, the Montana Freemen, and some "Christian militia" as groups that "can be placed under the category of far-right-wing terrorism" that "has a religious (Christian) component".[107]

In 1996 three men—Charles Barbee, Robert Berry and Jay Merelle—were charged with two bank robberies and bombings at the banks, a Spokane newspaper, and a Planned Parenthood office in Washington State. The men were anti-Semitic Christian Identity theorists who believed that God wanted them to carry out violent attacks and that such attacks will hasten the ascendancy of the Aryan race.[108]

In 2011, analyst Daryl Johnson of the United States Department of Homeland Security said that the Hutaree Christian militia movement possessed more weapons than the combined weapons holdings of all Islamic terror defendants charged in the US since the September 11 attacks.[109]

In 2015, Robert Doggart, a 63 year old mechanical engineer, was indicted for solicitation to commit a civil rights violation by intending to damage or destroy religious property after communicating that he intended to amass weapons to attack a Muslim enclave in Delaware County, New York.[110] Doggart, a member of several private militia groups, communicated to an FBI source in a phone call that he had an M4 carbine with "500 rounds of ammunition" that he intended to take to the Delaware County enclave, along with a handgun, molotov cocktails and a machete. The FBI source recorded him saying "if it gets down to the machete, we will cut them to shreds."[111] Doggart had previously travelled to a site in Dover, Tennessee described in chain emails as a "jihadist training camp", and found that the claims were wrong. Doggart pleaded guilty in an April plea bargain stating he had “willfully and knowingly sent a message in interstate commerce containing a true threat” to injure someone. The plea bargain was struck down by a judge because it did not contain enough facts to constitute a true threat.[112][113] Doggart stood as an independent candidate in Tennessee's 4th congressional district, losing with 6.4% of the vote.[114] He has a number of degrees from a degree mill and an ordination from an ordination mill. Various Muslim groups have declared Doggart a terrorist, though none of the charges against him are terrorism related.[115][116][117][118]

In November 2015, Robert Lewis Dear killed three and injured nine at the Planned Parenthood clinic in Colorado Springs, Colorado.[119] Dear voiced on several occasions his support for radical Christian views and interpretations of the Bible, and praised people who attacked abortion providers, saying they were doing "God's work." He also described members of the Army of God, a loosely organized group of anti-abortion Christian extremists that has claimed responsibility for a number of killings and bombings, as heroes.[120] In May 1991, Dear was arrested and convicted in Charleston, for the unlawful carrying of a "long blade knife" and illegal possession of a loaded gun.[121] A woman who was married to Dear from 1985 to 1993 told NBC News that Dear had targeted a Planned Parenthood clinic before, by putting glue on its locks, and had a history of violent behavior. In the court document for their 1993 divorce, his ex-wife said, "He claims to be a Christian and is extremely evangelistic, but does not follow the Bible in his actions. He says that as long as he believes he will be saved, he can do whatever he pleases. He is obsessed with the world coming to an end."
