This commission was faithfully fulfilled by the Apostles who, by their oral preaching, by example, and by observances handed on what they had received from the lips of Christ, from living with Him, and from what He did, or what they had learned through the prompting of the Holy Spirit.
Tendo hilo lilitimizwa kiaminifu na Mitume, ambao kwa kuhubiri kwa maneno, kwa mifano na kwa kuunda jumuiya mbalimbali waliwajulisha watu wote yale waliyopokea kutoka katika kinywa cha Kristo, kwa kuishi pamoja naye na kwa matendo yake; na pia yale waliyojifunza kwa uvuvio wa Roho Mtakatifu. Tena, tendo hilo lilitimizwa pia na wale, Mitume na wengine walioishi nao, ambao, kwa uvuvio wa Roho Mtakatifu mwenyewe, waliandika ujumbe wa wokovu[9].
