We have to distinguish between content and method. The content (the Gospel) is the ontological truth that can not be divorced from reality, thus that content may not be changed from generation to generation. The method is how the content is communicated which may be changed from generation to generation within objectively true (more content) moral limits.
Tradition does consist of both content and method. It is important that we recognize that no matter how old or new a truth-claim is, if it is false, it must be rejected; but if it is true, then it must be accepted. The historical event of the Resurrection of Jesus is the content that has not changed since the day it happened (1 Cor 15). Part of our discipling the next generation must include historical instruction- a defense of the historical event of the Resurrection (the ontological truth that must be passed down to the next generation).
But if a method of communication falls outside the limits of morality, then no matter how old or new it is, it must be abandoned. If it is within the limits, then it may continue to be used. The Apostle Paul stated that he adapted his method of communicating the Gospel not just to a new generation but to different cultures. Part of our discipling the next generation must also include moral instruction- ethical views (and a defense of the particular view based upon both moral content given in Scripture and logic) that will give them both freedom and limits to guide how they communicate what must be passed down.
While there will always be differences in preferred methods of communication from generation to generation, there will always be methods of communication that are within the moral boundaries. If we wish to communicate the truth of the Gospel to the next generation, we must be willing to recognize that there is much more moral freedom in our methods of communication than some people realize, and we need to make the choice to adapt the method to the next generation.
Tradition, when its claims are true, meet the new generation of people in the older generation's choice to change how that truth is communicated so that the new generation will understand it, accept it, and transmit it when they become the older generation.
