Spirituality is subjective. Christian spirituality would have to be centered on Jesus Christ, but cannot be about “who is Jesus for you”, as therefore Jesus could be anybody who fits your description of Jesus and not the gospel’s.
There can be many spirits, but only one Spirit from Jesus Christ. There can be many false Christs, but only one Christ from history, who can reveal himself to us today–the only true Jesus Christ as shown to us in the gospel. The question to our spirituality, from which Christian spirituality flows, is do we believe in this Christ?
