Well written, however the Holy Spirit is my tutor.
By the Holy Spirit, I presume you mean the wise counselor whom Jesus promised would guide His Church in all truth. If so, then He is either a fool and a liar, or He does not exist, because in matters as profound as baptism and as trivial as Harry Potter, He has guided thousands of different sects to hold, and to dispute quite uncharitably, many differing opinions.
The third possibility, that you are wrong and the Church is right about what the Holy Spirit teaches, is most probably the correct one.
