Finally I am certain of the truth of Orthodoxy. I am going to the local Antiochian parish tomorrow morning for Divine Liturgy. I visited Orthodox churches quite a while ago, and have been attending a Byzantine Catholic church, so am familiar with the liturgy and most of the customs. This parish uses English for all services, has vespers and orthros every weekend. The ROCOR church is closer, but is entirely in Slavonic with the sermon in Russian. The OCA churches are too far away. The Greek church is part-English, part-Greek; the Serbian and Ukrainian are comprised mostly of retirees and have Dvine Liturgy only.
I have no idea how long I should attend before asking about the catechumenate process, and then if that will take a few months or a year. Mostly what I have been working on lately is absorbing some of the concepts -- for me it takes a while for some of the differences in approach to sink in and fit with other ideas. The doctrines themselves are not a problem at all.
One thing I noticed about this parish when I stopped by to buy some materials one Sun. am was the good age mix, which is, imho, one sign of a healthy church.
I would welcome comments/correspondence from anyone with any useful comments.
