No. It's this new thing they got called "online giving". Of course they also take checks, which you can send to them but you have to have this thing called a "checkbook", and the church sends you these things they call "offering envelopes". They should come with the name of the church printed on the front, and the location of the church, and may also have your name and where you might be located. You will need to find this place called a "post office", where you can purchase these things called "postage stamps", you can then peel one of them off, and affix it to the aforementioned, offering envelope. The aforementioned checkbook has these things called "checks" inside. Now before you can get a checkbook, you need to go to this place commonly referred to as a "bank" or a "credit union". You will need to go there, and take some cash, and give it to someone at the bank. You may need to wait in a line in order to do so. The person you give it to, is usually someone who sits or stands behind a counter, and wears a badge with the emblem of the bank or credit union. Tell them that you want to open up an "account". They will give you a choice as to which type of account that you can choose from. Choose wisely, because some of them have recurring fees. They will give you a set of temporary checks or cheques if you live in the UK, and you can use those. It has a number of entries where you can write the name of the church that you wish to pay your tithe to, and the amount of the tithe in both numeric and word form, put the current date at the top, and sign your name at the bottom of the check. Then you can place the check into the aforementioned offering envelope. The envelope they send you is sealable, so you will want to seal it. Then you take the offering envelope, either to a post office, or you can use this thing called a "mailbox". Some of these mailboxes have a special compartment labelled "outgoing". Others have a flat piece of metal that is shaped like a flag. It swivels, so you will need to ensure that the piece of metal points straight up. You can open that mailbox, insert the offering envelope, and close it.
Important Note: Make sure that amount of money that you give the person at the bank or credit union, is greater than the amount that you write on the check, and be sure to keep track of the amount of money that is given at the bank or credit union, and the amount that is written on the check.
