My new local Bishop is unlikely to make much use of his CoA. He makes a great deal of being an "ordinary bloke" (hence his motto). His very first comment on hearing of his election was to the effect that now he would have to learn to eat his dinner properly with a knife and fork(!)
I was surprised to find that the arms were designed by Henrik Dahlström, the State Archives' heraldic artist, and thus someone who should know his job. But the so-called "Swedish cross" (as in the Swedish royal arms) is quite inappropriate. It is used in the royal arms to unite the quarters so that the arms are no longer quartered. In the Swedish fashion, Bishop Dalevi's arms
should be quartered 1&4 the bishop's see, 2&3 personal arms. As it is the arms appear to be united by the cross, which of course they are not. Bishop Dalevi's heir would use only
Gules an open Bible Argent on its dexter pages a Menorah and on its sinister pages an Ichthys in pale both Gules, not the united arms depicted below.
The arms of the current Archbishop of Uppsala show how it should be done - Q1&4 Uppsala, Q2&3 Jackelen.

Incidentally, the use of the cross and crook behind the arms of the Archbishop and just the crook behind the Bishop's arms does not seem to be anything to do with their respective ranks. Archbishop Jackelen used both when Bishop of Lund.
