ERB Frankfurt (Seal)

Working on a new branding for a church plant in Frankfurt. It should look classy, elegant and historic. I went for a »heraldic« look. It's one of many drafts. What do you think about this version? It's still work in progress and I'm thankful for any kind of feedback and suggestions. Thank you!

Update: You can find six variations in the attachments. Wich version would you choose?
