The Reverend Petaia Setu has accused the two of using land that belongs to the church to keep their cattle on, instead of taking them to their own properties.
He broke his silence after he was recently asked to resign when his wife became ill.
But the reverend insists the request for him to step down was made because he is outspoken and always questioned the many injustices in the church leadership.
Petaia said the church is materialistic and seeks wealth while people are suffering because of the financial demands by church leaders.
But the general secretary, the Reverend Tupu Folasa, has dismissed the allegations, saying the church is on the right path in administering its developments and affairs.
