Ferdinand Christian Baur quotes:

It rests with every professor of the religion of Jesus to settle within himself to which of the two religions, that of Jesus or that of Paul, he will adhere.

It was my study of the two Corinthian letters that first caused me to concentrate my attention more directly on the relation of the apostle Paul to the older apostles.

It must inquire not merely about the circumstances of the time in general, but in particular about the writer's position with regard to these things, the interests and motives, the leading ideas of his literary activity.

Without philosophy, history is always for me dead and dumb.

What kind of authority can there be for an 'Apostle' who, unlike the other Apostles, had never been prepared for the Apostolic office in Jesus' own school but had only later dared to claim the Apostolic office on the basis of his own authority? The only question comes to be how the apostle Paul appears in his Epistles to be so indifferent to the historical facts of the life of Jesus....He bears himself but little like a disciple who has received the doctrines and the principles which he preaches from the Master whose name he bears.

The greater the conceptual significance of a literary product, the more it should be assumed that it is based on an idea that determines the whole, and that the deeper consciousness of the time to which it belongs is reflected in it.
