While the following comment is directed towards LCG members, it is also standard practice in almost all the splinter groups to guilt trip members into sending in this so-called tithe. Besides not being a new covenant command any more than tithing is itself, this con-game is just one more way for the churches to increase their coffers. A lot of this money goes into sending LCG minions and other Feast location scouts in other COG's to search out vacation Feast sites and supposedly paying for convention halls, etc. Ask Lil'Jimmie Meredith how much fun he had "researching" Feast site locations.
Since the church itself requires that its members attend these "convocations" then the church itself should be paying for all the halls, sound rentals, video hookups, and satellite feeds, NOT the members. Each of these groups hauls in millions of dollars annually and certainly has the means to pay for these sites instead of coning members into double paying for everything they do at the Feast.
Tithe of the Festival Tithe—Repeat Announcement
For many decades, the Church of God has practiced what is called the “tithe of the Festival tithe.” What this means is that brethren who can afford it are asked to send a tenth of their Festival tithe to the Church in advance of the Feast, to help pay for meeting halls and other Feast expenses, as well as to help brethren around the world with limited resources to attend the Feast (Deuteronomy 14:27; 16:14). If you are able and you have not already done so, please send in your tithe of the Festival tithe for this year. This contribution is greatly appreciated.
