Above is the coat of arms of Archbishop Antje Jackelén, the Bishop of Lund in the Church of Sweden elected as the first woman to be Archbishop of Uppsala and Primate of the Church of Sweden. She was installed at Uppsala on June 15, 2014. Below is a photo of the new archbishop with (l.-r.) Crown Princess Victoria of Sweden, King Carl XVI Gustaf, Queen Silvia and Archbishop Anders Wejryd, her predecessor as archbishop. The coat of arms follows a typical pattern in Scandinavian countries of the personal arms (in the 2nd and 3rd quarters) being quartered with those of the (arch)diocese. The motto translates to, “God is Greater”.

EXARANDORUM 
“diocesan crest in quarters 1 and 4 / personal crest in quarters 2 and 3 are a typical pattern in Sandinavian countries” ……. this is partly true. I think this pattern is typical “German”, including Scandinavia. I don’t know exactly how this is for the Lutheran churches, but for the roman-catholic churches the pattern 1-4 diocesan, 2-3 personal is the base. Bruno Heim wrote also about this.
But we see in the new-created bishops crests in Northwest Europe a growing number of counter-examples, f.i. quarterly with the diocese in the first quarter and the other three all personal, or even: for quarters personal and also the diocesan crest as (fifth symbol) in an escutcheon of pretence (bishop Oster from Passau).
In Scandinavia and especially for the Lutheran churches the quality has been better maintained. In this region we see hardly overcrowded shields.
I didn’t say it was always done. I said it was. “Typical”. I didn’t say it was exclusive to Scandinavia. But it is present in Scandinavia.
But why not the archiepiscopal cross?
