Have nothing to do with the fruitless deeds of darkness, but rather expose them. For it is shameful even to mention what the disobedient do in secret. But everything exposed by the light becomes visible, for it is light that makes everything visible. This is why it is said:

         “Wake up, O sleeper,

         rise from the dead,

         and Christ will shine on you.”

Be very careful, then, how you live—not as unwise but as wise, making the most of every opportunity, because the days are evil. (Eph 5:11–16)

You will hear, over and over again, from United Church sources that the decision to allow Gretta Vosper, an avowed atheist, to continue in ministry as an ordained United Church Minister is nothing to worry about.  They will tell you that this decision, though troubling, is an isolated incident, which does not change the United Church in any substantial way. Do not drink the Kool-Aid.

To be a Church, that is to be an organisation which is in some way distinct from a social club - the Lions, or Kiwanis, is to have some attribute, central to its life and character, regarding God. The Unitarians are not, from what I can see, an actual church in the normal meaning of the word, for no particular belief in God, nor any belief in God at all, is required. (Is it a philosophical fellowship?)
There has been lively debate about the faithfulness of the United Church for many decades.
