No problem at all.
You have to give 10% of net earnings to the church? Is this true? Are there ever any issues with people not giving the full amount they are supposed to pay? What happens to the money? I assume lots is used for good causes or events.
We are commanded to give 10% of our increase to the church in tithes as well as make additional contributions.
As to what the 10% includes again has an element of discretion although some bishops will be more vocal about what that means. We pay 10% on our gross salary, most in this country I think pay it net. Some pay it on any cash or even equivalent value of item received, such as if they were given a car (perhaps a bit extreme but just to illustrate) they would say on 10% of its value. I don't know any personally that do that but I've seen some say they do on forums. Some pay on benefits, or pensions or other things but others don't. I even know of people who lag after all expenses and deductions. We are required to be full tithe payers to be able to have temple recommends which allows us to go into the temple, and essentially that's the standard expected. But no one would be kicked out for not doing so.
The money is mostly used for building of temples, and administration costs of running the church. All local ministers are lay, no one is paid. It's used for charity work and just the general real running of the church.
In addition, we are required to make fast offering, on the first Sunday of the month (usually) we fast for 24 to draw closer to God, we donate the money we would have paid for the meals of that day. That money is used for local relief of those in need, we call it welfare. So in theory a member in trouble can call to the bishop/minster for help and money is available to help.
We also have other funds, like missionary funds (our missionaries are self funded with help from membership), as well as education funds to help those mostly in poorer countries get an education, and specific funds for other things, like humanitarian efforts, although tithing also covers that. But when there is major crisis in the world members will donate additionally to that fund to help.
The church is well know for its aid, we own store houses and farms to help provide aid at very short notice.
Do many people find their future partners at events for the church?
As for marriage within the church some do, and some don't. I married "within" the church. It's kind of expected because we believe in marriage after death and that can only be down for sealing ordinances and therefore between members. But my husbands family all married outside the church, a lot do, the church is always much more popular with females for varying reasons and therefore it's hard. Some people stay single, other marry outside the church, just depends really.
When I was in my early 20s there was lots of activities held all over the country which kept me busy, I would think nothing of driving 4 hours in an evening to go to a dance and then turn around and drive back home, after a days work. To be honest I had a more active social life than many of my friends who were not members, I met my husband at a weekend convention where we did activities, had dances, had fun fair rides, had doctrine classes, but mostly just socialised.
I think the church does a lot less of those time of activities now, locally we have a camp festival thing once a year but I think it's all a lot less popular and there are no where near the amount of activities there were 10 years ago.
