Development of the Trinity of Persons

Bible readers can determine themselves that the terms “Trinity” and “three persons” is never used in regards to God in the text of Scripture. This does not necessarily make them wrong, but historians freely admit that the doctrine of the Trinity of persons developed (to the point we have it today) over a period of several hundred years. Was not the inspired writings and understanding of the apostles enough? Did we need to “develop” a doctrine beyond the writings of the apostles? Did the Holy Spirit determine the orthodoxy of the doctrine of the Trinity through inspiration or did the bishops collaborate and then vote on as though it was a political issue?
