Why do you recognize Acended Masters as your elder brothers and sisters and that
they can help you on the path of life?   

We are to call no man on earth masters as an infallible teacher or spiritula guide for one is our Master in heaven ,and in the same way we are call no man on earth holy father/papa, for one is our Holy Father/Papa in heaven .   Can you define the word "one" according to Catholic theology?

And call no man your father upon the earth: for one is your Father, which is in heaven.Neither be ye called masters: for one is your Master, even Christ.Mat 23:9
