"There are faithful Shepherds who care for the flock but there are also mercenary infidels who seek to scatter the flock and hand the sheep over to be devoured"

as it is written....

"For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
And no marvel; for Satan himself is transformed into an angel of light.
Therefore no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works" 2Cor11:13-15
