Is it an attempt to introduce the mantra to the followers of Jesus or is it to introduce Jesus to those who chant the mantra?

Is it an interfaith message? Or is it an attempt to ‘fool’ by inculturation.

Is it to emphasize that the mantra may be yours but the God must be ours? 
Why is there no acknowledgement of the source of the mantra?
Why Jesus, why not Krishna or at least both?
Will it become mantra minus Hinduism, just like yoga minus Hinduism?
