Hello Blain. People are called to serve in different capacities, it doesn't mean anyone is subhuman or that anyone is higher than anyone else, or that some service is more valuable than other service. Perhaps it's a mistake to look on the church as a hierarchy because:
Matthew 20: 25-27 Jesus called them together and said, “You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. Not so with you. Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave.
Matthew 23: 8 “But you are not to be called ‘Rabbi,’ for you have one Teacher, and you are all brothers"
