I agree with many of the comments so far . Reassure your daughter . Let her know you love her and will always want only the best for her . (Do not lie to her ...if you don't worship Jehovah don't say you do )
It is time to confront your wife . Indoctrinating your daughter against you is wrong and you should not tolerate it in your home .
I grew up in a 'divided ' household and from a very young age was told that one day my Father ,and unbelieving Grandparents may one day try to take me from my Mother ,and it was important for me to remain loyal to Jehovah on my own . This was when I was 5-6 yrs old ....this seriously stresses out a child and it should be a CRIME . It is emotionally abusive to thrust Armageddon fears upon young childrens minds .It caused me to never trust my Father or to be totally honest with him . This was a shame because it was all based on my Mom's imagined persecution possibility all based on Watchtower CRAPOLA ! It has only been in the last few years that I am actually having honest heart to heart conversations with my Dad ....he is 83 . Don't let this happen to you . You CAN prevent this outcome .
You need to have a serious talk with your wife . Stand up for your daughters well being ,mentally and emotionaly.Tell her what is acceptable ,child appropriate teaching and what is NOT .
What kind of life do you want for your children ?? It is up to you to provide it ,do not make the mistake of sitting back and letting your wife make all the decisions of the childs up-bringing . You are the Father and YOU have a big say in this you know .
