(CNN) The FBI and local law enforcement are working together regarding "threats of violence" and Virginia clergy leaders are urging prayer and peace as the state's capital braces for a guns rights rally on Monday -- a date which coincides with the celebration of Martin Luther King Jr's legacy.

"On the very day we set aside to honor the life and enduring legacy of Dr. King, these dark and dangerous forces threaten to converge on our city and our Commonwealth, bringing hate and violence," prominent faith leaders warned in a statement released Sunday. "In this difficult moment, and in the face of these threats, we seek to muster Dr. King's moral courage."

Meanwhile, a spokeswoman for the FBI Richmond field office said the agency "would provide assistance as deemed appropriate to ensure public safety."

Spokeswoman Dee Rybiski said in a statement: "In response to a request for assistance from the Virginia Division of Capitol Police, FBI Richmond has been working with our local and state law enforcement partners in relation to threats of violence at the rally on January 20, 2020."

Federal authorities arrested a number of suspected neo-Nazis around the country this week out of concern that they were planning violent acts at Monday's gun rights rally in Richmond, a senior FBI official said Friday. Seven men accused of belonging to a white supremacist group called The Base were arrested this week in separate raids in Delaware, Georgia, Maryland and Wisconsin, according to authorities.
