Many people who left the Church are NOT coming back.

For years, the Catholic Church has seen dramatic declines in Mass attendance. Many agree that the Catholic Church needs sweeping changes.

As science informs us, we are increasingly unlikely to believe unbelievable things.

Cities change. Churches change. How will we accommodate change, while retaining what is worthy in our cultures and traditions?

Should we be concerned that society is becoming more secular? Give me lovers, rather than believers, any day.

Some people want churches to focus on values, not just beliefs.

Recall that there are 45,000 Christian denominations, who almost never agree. Imagine that all 2.4 billion Christians agree that we should follow Jesus. What does it mean to follow Jesus?

What is the future of Christianity? Can Christianity be more experiential, more nuanced, and more respectful of science?

There are more than 45,000 forms of Christianity worldwide, and they disagree on the fundamentals. What beliefs are fundamental to Christianity?

Many people are leaving church over questions of belief or doctrine. How are people who are leaving church maintaining spiritual practices?

Many people are leaving church because of some speculative doctrines, supernatural beliefs, and unkind practices that they found in church. Where are they finding community after leaving church?

Christianity uniquely emphasizes creeds, exclusive claims and evangelization, compared to many other religions.

Since I wrote a book about asking questions, I'm meeting a lot of people who are asking questions. Many of them tell me, "I'm not 'out' with my doubt."

Sometimes, readers will ask me, "If you don't believe in a Supreme Being who creates the Universe and manages human affairs, then what do you believe?"

Jim Palmer, a friend and mentor who wrote the foreword to my book, recently posted a podcast episode called, "Is Christian Theism Dead?" for the Center for Non-Religious Spirituality.

Everyone is agnostic, but not everyone admits it. Sometimes, we confuse firmly-held beliefs with well-documented facts, but beliefs are not facts.

Many Christians assume that belief is the most important feature of religion, since belief is such an important feature of Christianity. However, in most religions, orthopraxy or right action is more important than orthodoxy or right belief. Community and practice are two aspects of orthopraxy.

All theology is speculation, and when we realize that there are almost 50,000 Christian denominations and that all of them have changed a lot in 2,000 years, we see how absurd it is to claim that any denomination, no matter how large or how old, contains "Truth with a capital T."
