Brother came out as gay and family members religious.

Hi there im hoping to get some advice on here, my brother has recently came out to our parents and with them being deeply religious was heartbreaking for them there was even tears from my mum n sister . Me on the otherhand was supportive and if he was unable to talk to our family i told him i loved him n he will always b my brother even offering him to move in cause he has been out the house most days. Ive even had debates with our parents about that we are human beings and can love anyone we choose they are so against it n my mum was in tears saying its wrong had to calm her tell her dont push him away. Now i dont know wot to do im stuck in the middle n will totally b there for my brother but my mother is breaking her heart that this is her only boy. I love them both i dont want to choose between family . Please need someone to talk to .
