Recently I have been confronted by statements that people “believe in Christianity”. I must say that upon reflection I do not believe in Christianity – I believe in Jesus.

SO here is a Kierkegaard quote:

The conflict about Christianity will no longer be doctrinal conflict (this is the conflict between orthodoxy and heterodoxy). The conflict (occasioned also by the social and communistic movements) will be about Christianity as an existence. The problem will become that of loving the ‘neighbour’; attention will be directed to Christ’s life, and Christianity will also become essentially accentuated in the direction of conformity to his life. The world has gradually consumed those masses of illusions and insulating walls with which we have protected ourselves so that the question remained simply one of Christianity as doctrine. The rebellion in the world shouts: We want to see action! (Soren Kierkegaard, Journals and Papers 4185)

To the above very-well phrased quote from Kierkegaard let me add: Christianity is not a doctrine, and not action alone, but a person! That is the paradox, the mystery, of the Single Individual – I am called to surrender myself to another person, I am called to a radical relationship to the Absolute – Jesus.
