Canada In July 2003, the hierarchy of the Catholic Church in Canada, the country's plurality religion, protested the
Chrétien government's plans to include same-sex couples in civil marriage. The church criticisms were accompanied by Vatican claims that Catholic politicians should vote according to their personal beliefs rather than the policy of the government. In late 2004,
Frederick Henry, Bishop of Calgary, wrote a pastoral letter saying "Since homosexuality, adultery, prostitution and pornography undermine the foundations of the family, the basis of society, then the State must use its coercive power to proscribe or curtail them in the interests of the common good."
United States In the United States, the leadership of the Catholic Church has taken an active and financial role in political campaigns across all states regarding same-sex marriage.
Human Rights Campaign said that the church spent nearly $2 million in 2012 toward unsuccessful campaigns against gay marriage in four states, as the second-largest donor representing a significant share of the contributions used to fund anti-gay marriage campaigns. A 2012
Pew Research Center poll indicated that Catholics in the United States who generally support gay marriage outnumber those who oppose it at 52 percent to 37 percent. In 2004,
George Hugh Niederauer, as Bishop of Salt Lake City, who opposed same-sex marriage, spoke against a proposal to include a ban against it in the Utah state constitution, saying that prohibition by law was sufficient. But in 2008, as Archbishop of
San Francisco, he campaigned in favor of California's
Proposition 8, a ballot measure to constitutionally recognize heterosexual marriage as the only valid marriage within California. Campaign finance records show he personally gave at least $6,000 to back the voter-approved ban and was instrumental in raising $1.5 million to put the proposition on the ballot. Subsequently, he called for an amendment to the US Constitution as "the only remedy in law against judicial activism" following the striking down of a number of state same-sex marriage bans by federal judges. In 2012, Catholic bishops in
Washington state issued pastoral statements and DVDs articulating the Catholic vision of marriage and urging parishioners to support efforts to define marriage as a union of one man and one woman in
Referendum 74. In 2010, the
United States Conference of Catholic Bishops (USCCB) clarified the criteria for the funding of community development programs by the Catholic Campaign for Human Development. One criterion was exclusion of organizations advancing activities that run counter to Catholic teaching, examples of which included those that support or promote same-sex marriage. In 2016, the President of the national bishops' conference denounced US Vice President
Joe Biden for officiating at the wedding of a same-sex couple, arguing that Catholic politicians should only do what is expressly in line with Catholic Church teaching.
Thomas Paprocki, Bishop of Springfield, Illinois, and Bishop
Robert Morlino of Madison, Wisconsin, have instructed priests not to allow church funerals for those in same-sex marriages or unions to avoid giving the appearance that the Church approved of such unions. ==Europe==
