Progressive Christianity

While looking for a church to attend here in Auckland I came upon these helpful descriptions of "Progressive Christianity." The phrase was used on several church websites and I got to thinking of how we get into our church speak with words like scriptural, Bible based, traditional "family oriented" (That has to be the most confusing and coded!) Others use the word emergent or emerging church. Even a simple and essential word like "welcoming" has different meanings! I get frustrated when one camp of the church takes a word or phrase and then tries to be the sole interpreter of its meaning or packs it with some hidden agenda.For example, shouldn't all churches be evangelical and welcoming? Or...if a church is not inclusive should it then proclaim itself as exclusive? Would the "uninitiated" have a clue of what we are talking about?
We use language strangely. Back in Albury we saw a cafe sign that advertised "Breakfast Served All Day Until 2 pm" I understand what they are saying but why not say "Breakfast Served until 2 pm." "All Day" just doesn't fit here! All Day but not after 2! Do we do that in our church talk? Bible believing...but... not about how to treat the poor. pray...forgive..etc. All welcome, but...
So keeping in mind,that too often terms and labels get bantered around without sharing definitions or conversation, I borrow this from St Luke's Presbyterian as they reflected on there ministry.

"....The Centre for Progressive Christianity and adopt the eight points of the Centre as reflecting the position St Lukes takes. The eight points are:

By calling ourselves progressive, we mean that we are Christians who…
1.Have found an approach to God through the life and teachings of Jesus
2.Recognize the faithfulness of other people who have other names for the way to God's realm, and acknowledge that their ways are true for them, as our ways are true for us;
3.Understand the sharing of bread and wine in Jesus' name to be a representation of an ancient vision of God's feast for all peoples;
4.Invite all people to participate in our community and worship life without insisting that they become like us in order to be acceptable (including but not limited to):
◦believers and agnostics,
◦conventional Christians and questioning skeptics,
◦women and men,
◦those of all sexual orientations and gender identities,
◦those of all races and cultures,
◦those of all classes and abilities,
◦those who hope for a better world and those who have lost hope;
5.Know that the way we behave toward one another and toward other people is the fullest expression of what we believe;
6.Find more grace in the search for understanding than we do in dogmatic certainty - more value in questioning than in absolutes;
7.Form ourselves into communities dedicated to equipping one another for the work we feel called to do: striving for peace and justice among all people, protecting and restoring the integrity of all God's creation, and bringing hope to those Jesus called the least of his sisters and brothers; and
8.Recognize that being followers of Jesus is costly, and entails selfless love, conscientious resistance to evil, and renunciation of privilege.

(PS whether you support all these principles or not, I think life in Christ will be progressive....progressive Christianity...making progress..to advance..to go forward.
Is anybody claiming Regressive Christianity?
