You can't. You have to make a looooong journey to do it! dumb answer
you need to get rank 10 warrior and rank 10 healer. And if you open the shop you can buy crimson paladin but mem only. and if you get that rank 10 warrior and healer you can get paladin.
Send Malum a thornax and that should get you started.
Be a Healer rank 10 and Warrior rank 10 and a member then go to swordhaven and talk to Artix. (You can also have rank 10 Acolyte instead of rank 10 Healer, and rank 10 Warlord instead of rank 10 Warrior)
you have to be a warrior rank 10 and a healer rank rank 10
warrior rank 10 and healer rank 10

The easy rank (known as Normal rank) can be found in Verdanturf town in Ruby and Sapphire. In Emerald, all ranks are in the Lilycove Pokemon Contest Center.
There is no rank 11 networker on mln since the highest rank is rank 10.
10 rank
10
You have to be rank 10 warrior and healer and upgraded. Then you have to do Artix's paladin quests, they are mostly really easy, all you do is kill Jack Sprat like 15 times, kill two swamp lurkers and kill werewolf in Willows Creek.
