When love becomes what Christianity is all about, we can make no sense of Jesus's death and resurrection.
Ask yourself: if that is what Jesus is all about - that is, getting us to love one another - then why did everyone reject him?
One of the problems with the identification of Christianity with love is how such a view turns out to be both anti-Semitic and anti-Catholic. The Jews and Catholics become identified with the law or dogma, in contrast to Protestant Christians, who are about love.
We don't fall in love and then get married; instead we get married and then learn what love requires.
Only the one true God can take the risk of ruling by relying on the power of humility and love.
