Stephen Heasley, formerly of Center Township, left, married Andrew Borg of Australia Sept. 23 in Butler County. The couple have filed a lawsuit against a company that substituted religious pamphlets for their wedding announcements.

BOSTON — Stephen Heasley, formerly of Butler County, and Andrew Borg were excited to see the wedding programs they ordered for their big day. But when the package arrived, the gay couple was horrified to instead find religious pamphlets with messages about temptation and sin, according to a federal lawsuit against printing company Vistaprint.

Butler County marriage license applications list Heasley, then of Center Township, and Borg of Sidney, Australia, where the couple now lives. The couple married Sept. 23 in Butler County.

The lawsuit, which was filed Tuesday in Massachusetts, accuses Vistaprint of attacking the couple because they’re gay by replacing their wedding program order with the “hateful, discriminatory” pamphlets.

“Our goal is to hold Vistaprint accountable for the harm they have caused, to give a voice to others who may have been similarly victimized, to help prevent this from happening to someone else and to send a message that there will be consequences for acts of hate perpetrated against others,” the couple said in a statement.

Vistaprint officials didn’t immediately respond to phone and email messages from The Associated Press on Wednesday. But the Dutch company, which has a regional headquarters in Massachusetts, told media outlets that it would never discriminate against its customers and is investigating the incident.

The lawsuit says the pamphlets received by the couple on the eve of their wedding included phrases such as “fight against Satan’s temptation and pursue what is good” and “do not set on the path of the wicked or walk in the way of evildoers.”

The couple says the pamphlets were designed to intimidate and threaten them.

David Gottlieb, an attorney for the couple, said they did not complain to Vistaprint at the time of their wedding because they had to scramble to print their own programs in time for the ceremony. Gottlieb said they hope that their lawsuit will bring public attention to the issue to ensure others don’t receive the same treatment.

The lawsuit, which seeks unspecified damages, accuses Vistaprint of discriminating against the couple because they’re gay and breaching a contract for not delivering the programs they ordered.
