and am now Lutheran (Wisconsin Synod). I Have always said a Creed. So many churches that do not like creeds do have a "Statement of Beliefs" which is, in fact, a creed, just not the Apostle's, Nicene or Athanasian. I think the aversion to those 3 main creeds is an anti-Catholic backlash.
I see this backlash disappearing. Most of my family is Catholic and many attend churches which focus on salvation by Grace and not works righteousness. As Lutherans, we are liturgical and follow the order of the church year, just like the Catholics, but with a strong emphasis on Grace and the Bible. I notice a huge interest among my Evangelical friends in Advent and Lent and what they are. These have no "magical" powers, they are just times to help us focus on things in the church and it's history and why we do what we do. I think as the anti-Catholic bias disappears, we will see more acceptance of things once considered off limits by many Protestants.
As for non-believers, there are hypocrites in every denomination and only God can judge the heart. I honestly have no idea if someone's outward actions are to make themselves feel good or are a genuine response to the love of the Lord. I just take everyone at face value and leave the rest to Him.
