Me and my high school best friend were Baptists and the other two closest to us friends were 7th day Adventist (all of us girls). Me and my friend didnt mind they were Adventists - we considered them as Christians and often went to their sermons and tried not to emphasize on the differences. We were curious what their faith was all about and asked many questions, sometimes argued in a friendly manner but always kept the good tone.
It was not the same with the other two girls. They never came to visit our church. They didnt want to tell us why, until one day, when one of them suddenly ... it slipped away from her. She told us our church was satanic and we are 'sheep going astray'. They didnt want to offend us, thats why they didnt tell us this in the first place. Me and my friend felt a little offended but forgot about it and kept the friendly relationship. So did they.
When contacting with people like 7th day Adventists you should know that they are very strict on keeping their beliefs(10th comandments). They believe that you are not saved for eternity when you only confess your sins and turn to God. They are confident that salvation has to be earned by the way you live each day on this earth. Thats why you have to be careful not to go aside from the right dids.We can say they live in fear of God more than in God's mersy.
By the way, they say they believe only in the Bible, but they have this prophet ...Elena Wait or something... who actually interprets the Bible in interesting ways which are not quite Biblical to me. On their sermons you can hear her quotations on equal terms as the Biblical ones. Bacause of her, they are considered as a sect since they have other sourses of belief exept from the Bible. This doesnt nesessaryly mean they are not Christians or true believers. I hope that some of them will be really saved - they believe in the same Lord like us, just they're different in some ways and only God will judge ALL OF US, what can we say?! But they are strange - be aware, they smile but they are not open since afraid not to lose the right way.
So, my advice. Ofcourse you can always invite your friend to your camp. But if she is a srong believer she will probably first ask her church co-members what they think about it and then she will most likely refuse to come. So, dont worry too much. But if she comes anyway, be prepared that she might find out some of your beliefs are not correct. If she is a good Adventist she will not argue, she would just like to go home. If she is not very clear with her faith yet, she might be happy to come to your camp and have new friends and...who knows, may be just there she might eventually meet with the Lord.
So, invitation is ok. Acception is up to her. If she likes to go home in the middle of the camp, her parents are responsible. Dont be angry with her. Dont feel guilty. Maybe you all will learn something out of this experience
God bless you
