Maybe 30 years afterwards.
Jesus words were passed on the same way other human deeds and words are passed on. Oral tradition, writing. Preservation of documents.
Passing it on requires people, and at some point it asks for your trust in people.
I am not sure what you are looking for.And this is a fact, that His exact words were passed on in the ways you describe or are you guessing?
Think about how family traditions are passed down. Frequently, siblings and friends will treasure events and favorite sayings of deceased family members. These will be repeated in an oral tradition. Some write them down. Now we have photographs also.
Larger historical families will be documented more widely than just our families. This is all part of human communication.
In Christ, we have Inspired revelation. Christ is the Son of God and Son of Man. Through Inspiration we have saving truth from God, passed on through human communication. The apostles treasured the words and deeds of Christ. They would have spoken about him to others (see the Acts). Even as Christ walked the earth, the Word spread. This is then committed to writing to preserve it.
This is all about people. The Church is made up of people who communicate the Gospel.
