A Texas megachurch embroiled in an abuse scandal involving its former pastor has announced it will be slashing staff following a dramatic drop in tithes.

Gateway Church elder Kenneth Fambro shared a financial update in a video message to staff this week, which was posted online by church watchdog blog Watchkeep.

The video's authenticity was reportedly confirmed by the church to local outlet WFAA.

"We have, in fact, seen our tithes reduce between 35 and 40%. As a result, we really need to go and start looking at the ministry itself and looking into some staff reductions," Fambro said.

"As leadership, we want to be as clear and transparent as possible as we walk everyone through this process."

"If your department is dissolved or reduced, you will receive the same severance package as those who took the voluntary severance," he said. "That is one month for every year of service up to four months." 

Fambro added that Gateway is seeking to "take care of our staff through this process", and admitted that staff reductions at the church have "not been handled well in the past".

"For that, I apologize. We really are trying to look at leadership differently and express leadership differently in doing so," he stated. "My heart goes out to everyone who is processing this right now. But know that we want what God wants. We want you to be exactly where God wants." 

Former pastor Robert Morris resigned in June after he was publicly accused of sexually assaulting a child in the 1980s.

Cindy Clemishire, the alleged victim, said that Morris had sexually abused her for several years, starting when she was twelve. 

Morris, who is now in his 60s, founded Gateway Church in 2000.

He has not faced any criminal charges.
