The Alliance Defending Freedom (ADF) has criticized a proposed civil unions bill in Colorado, saying it would violate religious freedoms.

The ADF is the leading group representing clients who claim gay marriage laws violate their Christian beliefs.

At a Senate committee hearing held last week, Kellie Fiedorek, litigation counsel with ADF, testified that the measure fails to “provide sufficient safeguards for the religious liberties of all Coloradans.”

According to the Denver Post, Fiedorek was the first of 15 witnesses to testify against the bill which is expected to become law.

Fiedorek criticized the bill for not extending religious exemptions to individuals and businesses.

The measure “proposes nothing to ensure that the government does not penalize, withhold benefits from, or refuse to contract with clergy, a religious institution, or a religious organization, not to mention individuals and businesses that possess sincere religious beliefs about sexual unions and/or the importance of both mothers and fathers to families,” Fiedorek said.

She added that the “extreme narrowness of those protections suggests intent to legislate prejudice toward individuals who possess deeply held religious beliefs about sexual unions or marriage.”

Fiedorek also testified against a proposed bill in Rhode Island which seeks to extend marriage rights to gay and lesbian couples.
