Please note there's no mention of ability score boosts. Some people think there should be ability score boosts. The WotC web enhancement has stats for Erbin at various divine ranks. At Divine Rank 0, he's only a Rogue 1, but his stats are astronomical. There's no explanation of how this former "beggar and petty street thief" has a low stat of 24, and a high stat of 40. I guess those are the stats he had as a mortal beggar and petty street thief, if he didn't get them from attaining Divine Rank 0.
Either way, the whole notion of deities is kind of vague. The book encourages you to make up your own system of divinity, and to alter the deities' stats to fit your system, your campaign, and your power levels. So another valid answer to your question would be "whatever you want"
