Probably not even then. The way I read Acts, the disciples were pretty clueless right up to the point of the Ascension, since they were standing around gaping up at the sky like turkeys in a rainstorm when the angel told them to get moving.
Even at Pentecost, 40 or so days later, when the Holy Spirit descended on them, allowing them to preach in tongues, they weren’t “organized” in the sense that they had codified their creed and established a church hierarchy. The need to become organized is dealt with slightly in Acts 6, when the need for the appointing of deacons (for lack of a better word) arises. This continues throughout the First Century, as churches are established in Greece and other areas further from Israel.
