Defending Christianity in our time became unpopular "private" shy and... poor. Catholic
fundamental theology - officially responsible for defending faith on behalf of the Catholic
Church - is aware of being in crisis: crisis of identity and content and... popularity. It
needs a new overall structure: a new point of departure and a new "spirit". It was offered by
Joseph Ratzinger Krzysztof Kaucha declares. Almost everything that has been recently used to
undermine the Christian faith and Christianity is used by Ratzinger to... defend Christianity.
Kaucha offers over a dozen arguments for Christianity based on Ratzinger's writings (and his
original thinking): the Christian axiom as an argument for Christianity Jesus Christ as the
proof of the existence of God Divine Revelation as an unending proof of God's existence the
alternative argument the argument from definitive novelty the argument from the absence of
someone greater than Jesus argument from truth the anthropological argument the argument
from forgiveness the argument "from reason" the argument from faith Ratzinger's wager (in
analogy to the famous Pascal's wager) the argument from the whole truth (many times very
painful for Christians) about Christianity the argument from the whole truth (many times very
shameful for Catholics) about the Church comparative argument no. 1 (Christianity versus other
Religions) comparative argument no. 2 (Christianity versus the ever more secularized world).
