What happened during the forty days spoken of here? This was the most important issue to the early church, and yet no one can say what happened. The Catholic church asserts that the doctrines and ordinances that make up the Church were set forth during this time, and yet they can't say what exactly was taught, or account for the fact that the doctrines that now define the church came about over the course of thousands of years as the result of human reasoning. Is it important to know what Christ taught his disciples during the forty days immediately following his resurrection?
