As long as the West maintains that "first" means "superior" we will not even be able to come to an agreement to convene an Ecumenical Council, let alone hash out theological differences.
When the names of all the Apostles are listed, Peter is always first. Judas Iscariot, the Lords traitor, is always listed last (cf. Matt. 10:2-5; Mark 3:16-19; Luke 6:14-17; and Acts 1:13). Sometimes Scripture speaks simply of Simon Peter and the rest of the Apostles or Peter and his companions (cf. Luke 9:32; Mark 16:7; Acts 2:37), showing that he had a special role that represented the entire apostolic college. Often, Scripture shows Simon Peter as spokesman for the entire apostolic college, as if he were the voice of the Church (cf. Mat. 18:21; Mark 8:29; Luke 8:45; Luke 12:41; John 6:68-69).
No church can run "on consensus".
