Please help

I was wondering if anyone could help me with translation to a cpl of phrases. I will use one of these as my Motto for an occult order, eg Frater xxxxx xxxxx, so they need to be as condensed as possible while being accurate. I would really appreciate any help or suggestions people could offer and will repay the favor if I am able. The phrases are :

He who seeketh the name of his Angel
He who seeketh his Angel
He who seeketh the snake

Thanks again.
