Christian values are the values that the church espouses. Secular values are the ones that secular institutions tend to promote.
Do you know where those differ? Let me show you an example:
 From The Affirmations of Humanism: "We deplore efforts to denigrate human intelligence ... We believe in optimism rather than pessimism, hope rather than despair ... We believe in the common moral decencies: altruism, integrity, honesty, truthfulness, responsibility ... We believe in the fullest realization of the best and noblest that we are capable of as human beings."
