The United Church of Canada, "a historically inclusive and open-minded Protestant denomination" according to the article in the Star, has at least been willing to take a stand that its ministers need to believe in God. Vosper in an interview with the Washington Post said, “We don’t talk about God,” and then added that the church needs to give up “the idolatry of a theistic god.”
The correct term for Gretta Vosper is not atheist, but apostate. She has, like Bart Ehrman to cite a famous example, abandoned the faith that she previously professed. It doesn't really matter what Vosper wants to replace God with, according to the Star interview, it is "adopting a more metaphorical interpretation of religious symbols and a greater emphasis on humanist, environmental and social justice causes." Without God, whatever you put in his place, is meaningless and void. This shouldn't be controversial in the least, that Vosper has been allowed to continue down this path for years should be shocking.
There is no way, at all, to apply the term "Christian" to what she is doing. What we believe matters, for our hearts determine our actions, not the other way around, as Jesus said, "out of the abundance of the heart his mouth speaks" (Luke 6:45) The heart of the Gospel is that mankind apart from God is lost in sin, we are hopeless on our own, and thus our ONLY hope is in salvation by grace through faith in the death and resurrection of Jesus. These beliefs are not optional, they're essential in every way.
A "Christian", let alone a minister, who does not believe in God, AND more than that, who does not embrace the Gospel, would be a nonsense proposition to John Calvin, Martin Luther, Thomas Aquinas, St. Augustine, the Apostle Paul, the Apostle Peter, and of course Jesus himself. For two thousand years the Church has proclaimed the Truth of the resurrection of Jesus Christ from the dead in victory over sin and death. To share the Gospel and make disciples of Jesus' followers, is why the Church exists.
Gretta Vosper may think that it is a "sad day" when 19 out of 23 members of a committee vote that an Apostate minister is unfit to lead the Church of Jesus Christ, I happen to see it as a "sad day" that 4 of the 23 voted to allow her to remain.
For additional consideration, Vosper's Church, West Hill, officially ended its use of the Lord's Prayer among other prayers, rewriting them along with classic hymns, for example:
From The Lord’s Prayer...
Then:
Our loving God, who art in heaven, hallowed be Thy name, Thy kingdom come, Thy will be done, on earth as it is in heaven. Give us this day our daily bread; and forgive us our trespasses …
To Words of Commitment...
Now:
As I live every day, I want to be a channel for peace. May I bring love where there is hatred and healing where there is hurt; joy where there is sadness, and hope where there is fear …
From “How Great Art Thou Art …”
Then sings my soul, my Savior God, to Thee,
How great Thou art! How great Thou art!
Then sings my soul, My Savior God, to Thee,
How great Thou art! How great Thou art!
By Carl G. Boberg
To “Then Sings My Soul …”
Then sings my soul in wonder, full and free,
amazed at all I hear and see!
Then sings my soul in wonder, full and free,
a sacred gift is life to me!
By Gretta Vosper and Scott Kearns (2007)
