I don’t think it is a choice to be ignorant. In fact they are taught to fear tradition as something evil. A misreading of the Traditions of Men, vs those things that Christ instructed the Apostles in. In the Gospels we read that after our Lord spoke to the crowds he took the Apostles aside and taught them further, explaining more fully what he had just taught to the crowds. What He told them was not recorded in the Scriptures, but passed down from the Apostles to their successors, those they laid hands on, and appointed to be the first Bishops and priests of the Church.
We can see that they believed they had authority not to innovate, or create new doctrines, but they felt comfortable in fully fleshing out what our Lord had instructed them in. For example the creation of Deacons. This was an act that the Apostles did on their own, something they obviously felt that they had the authority to do.
Our Lord ordained the Apostles when on Holy Thursday He instructed them to do what He did at the last supper, (take bread and wine, thank the Father, and bless it, so that it would become His body and blood) He later laid hands on them and breathed on them and told them they now had the authority to forgive sins, (Something until that time only He, the Father and the Holy Ghost had the authority to do.) He shared His authority with them. When the Annanias and Saphrriah lied to the Apostles it was found to be equivalent of lying to the Holy Ghost. Why, because they where intrusted with the authority given them (by virtue of the office they now held, as they remained men, capable of sin and error) so to lie to them was the same as trying to conseal the truth from the Holy Ghost. Why because they had been given an office that had authority and based on the dignity of the office, where did that dignity come from? From Christ who gave them the office, and instilled the dignity into that office. What you may ask does this have to do with Tradition, as it is clearly Biblical (thus far) you may ask. As a foundation for the Authority given to the Church in the office of the Bishop, I have laid down the basic authority of the Bishop
from the New Testament. (There are numerous other Bibilical citations that could be added, but I think those above are enough for now.) We combine that with the Scriptures in which St. Paul tells his desciples to “Hold fast to the Traditions that I have taught you.” and we see there are two different Traditions that the Bible speaks of. Holy Tradition, that taught by Christ to the Apostles, and from the Apostles to their successors, later when times of persecution had calmed. The second the Traditions of Men, rejected by the Church. The Traditions of Men can be found in the teachings of heretical sects that arose, for example the Gnostics.
