Changing initiate career to zealot career, still able to use blessings?

By drallcome, in Warhammer Fantasy Roleplay

Hello again If a player wants to change careers from initiate (before they have completed initiate) to zealot will they lose all of there blessings? and if they cannot does that mean any career can then use blessing?

I suppose I just dont see any disadvantages from changing a career early other than you need to spend the appreate number of advances?

Thank you guys again for the help

-also I see some people refering to a "FAQ" where would I find that so that I dont have to keep bothering you guys?

Thank you very much ! it answers so many questions : )
