The article in the OP doesn't not say there was a pre arranged deal. It says that became the ultimatum once the pastor saw the photos of the deceased kissing her wife. The article also states:
Friends say they gave the church a remembrance video of Collier a week before that contained images of her kissing and embracing her wife. The pastor had every chance to stop the funeral long before it began, they said.
Collier's friends say they still haven't been reimbursed by New Hope Ministry for the cost of the funeral.
Moral to the story, if you want something "YOUR WAY", hire someone willing to give it to you. Don't expect others to cowtail and compromise their beliefs to accommodate you. Especially when those beliefs are made known up front and ignored by the one who hired you.
I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. - MLK
After coming to the realization that the family of this woman had not complied with his stipulations the pastor was in a no win situation. Had he gone on with the service at that point no one would have ever heard a word about it and the pastor would have been left with the knowledge that people walked into his house and treated him like a punk. Choosing to stand up for himself has brought down a whole boatload of negative publicity.
He made the decision he made and I feel bad for the guy but I feel worse for the woman who's legacy is now tainted by this.
Is RIP really too much to ask?
