Seems to me that the hierarchy is present in various ways in sacred scripture as well as in sacred tradition. Saint Paul gives a list of gifts that are offices (or people) when he writes:
first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. (1Cor 12:28)
And his instructions to Timothy and Titus imply that he gave authority to those sainted men to ordain others into the presbytery of the church.
Titus 1:5-6 DRB
(5) For this cause I left thee in Crete: that thou shouldest set in order the things that are wanting and shouldest ordain priests in every city, as I also appointed thee:
(6) If any be without crime, the husband of one wife. having faithful children, not accused of riot or unruly.
The idea of hierarchy within the offices of leadership within the church arose in apostolic times. That it firmed up and evolved with time is no surprise since everything in Christianity appears to have begun in apostolic times and to have firmed up and evolved in subsequent ages.
The same is true of baptism, its application to households is in scripture and its connection to circumcision is in scripture too so it is to be expected that baptism was at first applied to converts and then to whole families and then to the progeny of Christian parents. This is how it was in ancient times with circumcision; First Abraham then his household then his children and their children etcetera.
It is also true of the Canon; first the old testament is 'converted' by the teaching of Christ then the apostles and prophets of the new testament add to the body of sacred scriptures and finally the church collects their writings and uses them in her liturgy and creating a list of books that are acceptable for liturgical use and the list becomes the canon of sacred scripture.
Development with the passage of time is both expected and necessary. That we have such discussions as this in GT is a witness to the necessity of development because if it were not necessary then no one would want to know what books are to be used in the liturgy of the church and nobody would have collected the writings of the apostles for inclusion in the scriptures. Christians would have continued as they were on the Day on Pentecost with the Spirit leading and teaching and no writings to refer to because the Spirit would be leading into all truth - as some say he leads them today, though each who makes such a claim differs from the others making similar claims.
The desire for apostolic authenticity produced the impetus to collect the apostolic writings (including the writings of those who were the friends and helpers of the apostles) and to use only those writings that the church as a whole regarded as genuinely apostolic in the liturgy. So the canon, like baptism and the hierarchy, arose in apostolic times and evolved until it became a list of books accounted by the church to be truly apostolic and suitable for teaching the church in the liturgy.
