However you can write yourself out of eternal life by doing the things the bible states you should not do, put simply.
So to marry your step cousin is not really a good choice.
The only problem you will have is more then likely your family not understanding. Fallow your heart if it's legal gods way and our laws way. we can marry an actual cousin (doesn't have to be a step cousin) but I'd say that is not wise. There is no blood relationship whatsoever and some step-siblings have never even met each other until years after their separate parents decided to marry each other.
It's tough because my aunt told me she won't ever forgive me if we end up together.
: D But I haven't seen my ex in many years, he and his dad are not close, to put it mildly. "step" indicates family member by parents who were married previously ...children from previous marriage become new spouses "step children" - NON-biological children step-brother/sister is a non-biological sibling .."siblings" due to parents remarriage"step children" are product of BLENDED families There are laws against marrying cousins due to biological reasons today however a step-cousin is not a biological cousinthere is nothing wrong from Gods Word, or morally wrong marrying a "step cousin" which is a term used to indicate they are now related due to remarriage of aunts/uncles with children ...a non-biological relative this is in reply to the person who said you could marry your step brother. A marriage is void if one party to the marriage is related to the other as:(1)an ancestor or descendant, by blood or adoption,(2)a brother or sister, of the whole or half blood or by adoption,(3)a parent's brother or sister, of the whole or half blood or by adoption,or(4)a son or daughter of a brother or sister, of the whole or half blood or by adoption.
as a Christian it does matter if you are with your step cousin,no matter how far removed.
