Luther didn't like it either. He considered it "not helpful" and it was included in his Antilegomena, a list with parts of the bible that were disputed and not necessarily considered genuine.
These days tourism is the most important sector of the economy. That might be so but it doesn't mean that it is as infested with tourists as other Greek islands. It's actually quite all right. Even in summer it is easy to find a room. When you arrive by boat the first thing you will notice is a bunch of people at the harbor that are screaming as if they're at a stoning. No worries, these are the hotel owners that are trying to offer you a room. They only want your best so no reason to be alarmed. It's quite common in Greece to pick up tourists at the port. At first the whole things appears to be a bit chaotic but once you get used to the shouting and haggling you might as well enjoy it. A lot of competition means you are likely to get a fair price.

Worth visiting on Patmos is the famous monastery of St. John the divine (Moni Agios Christodulos). Its library is well known all over the world and considered to the host the most important collection of historical documents in the Greek Orthodox world.
There are a number of monasteries on Patmos that are dedicated to John. You won't be surprised to hear that Patmos is an important destination for Christian pilgrims. Very popular with them is the cave where Saint John received the revelation from Jesus. It's also known as the "Cave of the Apocalypse". I know that sounds a bit scary but its safe. The cave is recognised by the UNESCO and protected under their world heritage program.
Even if you are not a pilgrim you'll enjoy the visit. Patmos is beautiful. There are many small inlets and bays with excellent beaches. Most of them are shingle beaches but that doesn't make them less pretty. I personally prefer them to sand beaches especially when it is a little bit windy.
Patmos capital is Skala. This is where you arrive and where you'll find most of the restaurants and rooms for rent. Stefanos Camping – the only camp site on the island - is about 2 kilometres away. Historically the capitol was Hora. It's half an hour walk away from Skala and a lot less touristy. Depending on what you want you might as well stay there.
By bus you get to the beautiful little fishing village Grikos and also to Kampos with its excellent sandy beach.
