“Now, having fulfilled the obligations of the church, he is apparently a real Christian and able to be a true priest.”

Apparently, according to the traditions and doctrines of men.

Mark 7:7-9

7 But in vain do they worship me, teaching for doctrines the commandments of men. 8 For laying aside the commandment of God, you hold the tradition of men, as the washing of pots and cups: and many other such things you do. 9 And he said unto them, Full well you reject the commandment of God, that you may keep your own tradition.
