Christian conservative Bryan Fischer and the National Organization for Marriage (NOM) are among those cheering Alabama Chief Justice Roy Moore's effort to block gay and lesbian couples from marrying in Alabama.

Moore on Wednesday issued an administrative order which stated that the state's laws which exclude gay couples from marriage remain in effect and that probate judges have a “ministerial duty” to enforce them despite a Supreme Court finding that gay couples have a constitutional right to marry.

Democratic presidential candidate Hillary Clinton criticized Moore's order as “unconstitutional” and the Southern Poverty Law Center (SPLC) filed an ethics complaint against Moore, asking for his removal from the bench.

Federal prosecutors also weighed in, saying that Alabama probate judges should obey the high court's ruling.

In a tweet to followers, Fischer, the host of American Family Association's (AFA) Focal Point radio show and a vocal opponent of LGBT rights, praised Moore for “upholding the constitution.”

“Judge Moore the only one upholding Constitution, which reserves marriage to the states. Civil obedience, not disobedience,” he messaged to his 8,541 followers.

“Note to GOP candidates: sodomy-based marriage is NOT the 'law of the land.' SCOTUS CANNOT make law. Art. 1, Sec. 1,” Fischer added in a separate tweet.

NOM, the largest group working to undermine the high court's marriage ruling, said that Moore's advice to judges was “consistent with the developing resistance in America to the Supreme Court's attempt to legislate from the bench when it comes to marriage, ignoring the federal constitution in the process and inventing out of thin air a 'right' to same-sex marriage.”

“The American people reject [the] judicial activism of the US Supreme Court and their attempt to redefine marriage. They continue to support marriage as it has existed throughout our nation's history, the union of one man and one woman,” the group added, ignoring national polls which show that a majority (59%) of Americans support the Supreme Court's ruling on the issue.
