But while the outspoken religious actor has expressed his opposition in the past to same-sex unions, he says Christians have have greater concerns other than gay marriage.
"When people get too focused on redefining marriage, you're distracted from the bigger problem - fornicators and adulterers," Cameron told Alabama's AL.com. "If the people sitting in the pews are fornicators and adulterers, the church will destroy marriages much more quickly than those outside the church. When God's people mock marriage, God doesn't take that lightly."
Cameron added, "I think the greatest threat to marriage is not other people's definition of marriage. The church isn't taking God's definition of marriage seriously. It's not other people sabotaging marriage that's the problem."
The former Growing Pains star also noted that "the church determines the moral temperature of the culture. On our watch we've let morality decay, the commitment to love and marriage fall apart. We've given in to an anti-biblical Christian worldview. We're simply failing to do our job as the church. Other people are moving into the leadership positions and steering the car right off the cliff. They're not the problem. It's those in the church who have taken their hands off the wheel and given up our place in the driver's seat."
