The Hierophant can challenge you to find your own position. You were brought up in a certain way - either accepted the tradition of your community (religion, values, rituals, we all have the imprint of our upbringing even if our parents rejected religion - then this rejection is our imprint), or you rebelled against it.
Now you have to find your own position. Simply imitating and duplicating what you were taught is not enough, and rejecting it as act of rebellion is no better. Ask yourself how you really stand in the lines of tradition sketched by your elders, and which path you personally want to go. That's a sign of personal maturity, and it's also part of a life long journey.
I like and respect the Hierophant. In a world of doubts, he is secure in his beliefs. And he asks us to find our own spot between the doubts and the certainty. Even if this spot is not our permanent home but just a step on the way. And whether we share his belief and tradition or not, he still gives his blessing.
Do you know German? There's a verse by Goethe that I'm always reminded of with the HIerophant.
Was du ererbt von deinen Vätern,
erwirb es, um es zu besitzen.
What you inherited from your forebears,
earn it to make it yours.
For me, that's one of his lessons and challenges.
