Would have been an excellent opportunity to see how much cultural influence the Catholic Church and other religious groups might still have by that time
Phlox said something about celebrating mass at the Vatican, but judging from this

I am not a religous person myself, but to think that religion will be gone by the time of "Enterprise" is not very realistic, in my opinion. The population on this world will continue to grow, and although some people will turn their back on religion, it is impossible to believe that everyone will in 200 years.
