That depends on your denomination in the modern day. The Apostolic churches (Catholic, Coptic, Orthodox etc.) trace their lineage through the apostles and have what is called Apostolic Succession. But the early church worked through the Apostles and who they taught and ordained. For example St. John who was a disciple of Christ taught St. Ignatius of Antioch who then taught Polycarp the bishop of Smyrna so on and so forth.
The first half of the service was for all and the second half was for Baptized members to partake in the Eucharist (communion).
Not sure how Orthodox do it now but in the modern day Catholic priests do seminary through a priestly fraternal order (St. Peter, Franciscans, Augustianians, Jesuits,) etc. there is still apostolic succession but different orders emphasize different things and might do mass differently. For example the Fraternity of St Peter is a traditional mass order.
Protestants have theological seminaries tied to their denomination. Calvinist, Lutheran etc. and often according to their specific church in their denomination. My Uncle was a Lutheran pastor who went to a LCMC Lutheran seminary. So the LCMC (leans conservative) LCMS (very conservative) and the ELCA (woke garbage). Will have different seminaries for their denominations.
With all the different Protestant denominations I can’t speak for all of them but that is how it generally works.
