Is there anything wrong with a Catholic priest dancing with a masquerade?

A Catholic priest pictured above dancing with a masquerade at a funeral in Nnewi, Anambra state. The photos were shared on Facebook and many Christians think its unacceptable, arguing that as a priest, he should not be mingling with an "unbeliever", the masquerade. Some others feel there's nothing wrong with this. What do you think? Please share your thoughts. Photo credit: Joel Sampson
