Can an iglesia ni cristo member date someone outside their religion?

I'm a member of INC, and my answer to that question is NO. You all know that the basis of our faith is the BIBLE, so everything we do is what God wants us to do. We can't have any commitment with a non-member except for friendship. I really can't tell you why because may be you just couldn't understand me or get my point. If you are really interested about that you can visit one of our locale near to your place. Thanks!

Everything they do is what the INC administration wants them to do but makes them think it's what God wants them to do.

Here's the deal. The INC uses 2 Corinthians 6:14 as their basis to not allow members to date or marry non-members (non-believers).

2 Cor. 6:14 reads:

"Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?

However, the INC ministers choose to use the George Lamsa Bible translation of the same verse which reads:

"Do not unite in marriage with unbelievers, for what fellowship has righteousness with iniquity? Or what mingling has light with darkness?

And of course you are not a believer if you do not accept founder Felix Manalo's messenger of God prophecies and the INC administration rules. It doesn't matter to them if you are of the Christian faith you still won't be allowed to date or marry someone who is a member of the Iglesia ni Cristo (INC) because you don't meet there requirements as a true believer. If you do date someone who is a member it will have to be way way on the DL because the members are threatened with expulsion from the church for that offense. Expulsion = an eternity in the lake of fire...hell. The INC has a very firm hold their members.

I think we can understand what's going on without going to an INC locale (church). I would expect an actual member to be able to explain the reasoning behind their beliefs.
