Christ centered worship, to answer the OP, is worship that has its entire focus on Christ.
That being said, there is more to Christ than Death, Burial and Resurrection. How about time on the incarnation or his ministry.
A class mate recently told me he was at a church where they had a guest preacher that was "fishing for Amens" so he'd say things like "Jesus was completely God." "Jesus died on the cross for the sins of the world." etc. etc. He then said "Jesus was completely human." Only about 2 or 3 people said Amen because that part of Christ had not been focused on.
I think our worship service is Christ centered. Once we get past the 4 or 5 minutes of announcements at the beginning (I'm w/ Marcia on this one) we usually sing 2 or 3 songs that work on building a message (usually some kind of theme) We'll then have a time of prayer. Sometimes we'll read over part of a confession of faith, or have "1 sentence prayer time" where the congregation can give thanks to God for various things. Then we'll sing a couple more songs, then offering then an expositional message.
It is quite different than what I'm used to. I'm used to 1 hymn, greet, 2 hymns, offering, sermon 1 hymn and we're done (where the hymns were seemingly chosen at random)
I just read over this and realized that it sounds as if Christ centered is a "Program" that you must follow -- that's not what I'm saying. I think Christ centered worship is deliberately choosing the 'activities' of the service so as to focus the congregation's attention on Christ.
