So they justify not being socialist according to this verse by the word believers. They don’t want to share with non-believers or even believers of other denominations (they are also non-believers since they aren’t exactly the same). So they can be non-socialist and just tithe and think it’s fine
But tithing doesn’t go to directly to people based on need. There are poor people in every denomination. They clearly don’t interpret this literally.
The tithe is an Old Testament standard. The New Testament says that they should give whatever the pastor asks. If the pastor asks for 30%, they are theologically supposed to give 30%.
There is actually nothing in the bible about giving in accordance to what a “pastor” says. I am not sure where you got that from. While you are correct that the “tithe” as described in the OT no longer applies because we are not giveing to the temple, Jesus’ command is to give freely, abundantly, and sacrificially out if s cheerful heart. The jews at Jesus’ time would have actually given a good bit more than 10% because of the various annual festivals that also required a percent to be given. What they were giving was in support of the upkeep of the temple and the priestly line who was prohibited from working elsewhere. For Christians, there is no priestly line. We have two offices according to the NT, Elder and deacon. Neither of these are entitled to financial compensation because of the title. Where we get that we should compensate them for their work from the command that a laborers should not be without his wages, and many pastors are doing work that amounts to a full time job. The fact of the matter right now is that most “pastors” across the world are bivocational meaning that they hold other jobs if time allows.
