I think that Eko is still repenting the murders he committed. Building a church is his way of getting closer to god, and I'm sure he is hoping to bring back or lead other losties to god. It's also another example of what Bernard was complaining about--by building a church, Eko is showing that getting off the island is not his priority. He is embracing the situation he is in and trying to heighten his spirituality. Not all that interesting, imho...
I'm still not convinced it's a church. Bernard pressed Eko as to what they were building but Charlie was the one to say that they were building a church.
Last we saw, Eko wouldn't tell Charlie what he was building either. For all we know Charlie assumed it would be a church so that's what he told Bernie.
well since he was a drug dealer and did other bad things like that, I think he has become very greatful and religious and wants to apoligize for his sins, etc.
I believe Eko ordained himself as a Catholic priest.
when he visited Henry and confessed to killing the 2 people on the island he did it to prepare himself for receiving the Sacrament of Holy Orders which is ordination. And I think when he cut his beard it was a symbolic tonsure which would permit him to act in the capacity of a priest. Tonsure: "A sacred rite instituted by the Church by which a baptized and confirmed Christian is received into the clerical order by the shearing of his hair and the investment with the surplice.(a surplice is the loose fitting garment worn at mass) The person thus tonsured becomes a partaker of the common privileges and obligations of the clerical state and is prepared for the reception of orders. The tonsure itself is not an ordination properly so called, nor a true order. It is rather a simple ascription of a person to the Divine service in such things as are common to all clerics."
That's still a pretty whacked form of Christianity.
It all matters very little in the end, however, because apparently "God can't see the island"...maybe a church'll get the big guy's attention (or maybe it'll attract "His" attention, and that can't be good.
I give the church two days at most. There's one thing Dharmatologists hate more than trying to escape the island, and that's worshiping a god that isn't theirs. and no they're not secret skin doctors.
