It certainly is not a testimony of Scripture. He was raised Catholic, and thus it is no surprise that he was spiritually dead, and thus he joined a cult in which the leadership is the supreme authority, with both Scripture and adherents being made servants to support it, as they can do no other.
He then becomes disenchanted with that one and joins another group in which the leadership is the supreme authority, with both Scripture and adherents being made servants to support it, as they can do no other.
The Lord surely has compassion on those who bounce from one spiritual trap to another. Hopefully the man will rest in the finished work of Christ eventually and leave the blind guides to fall into their own ditch!
