Here is the clearest picture I have found yet, if it helps beyond what I’ve shown already.
I sent a message to the church using their contact form.
In the latest picture, it looks kind of like a serpent to me.
Which church?
I assume the church I posted about?
The crown is the top part of a heart; the symbols the rest. I can’t figure out the serpent squiggle, either.
Perhaps they’re a Lutheran version of the 12 consecration crosses that Catholic churches have? In Catholic churches they’re generally spaced regularly around the church though, not all together in the one place.
Catholics have 14 Stations of the Cross spread around on the (usually side) walls. This does not appear to be anything like that.
I have been in more Lutheran churches than any other in recent years - for some reason, they are the go-to place for small concerts and performances when secular halls aren’t available. Even though I was raised in a Lutheran family, every one of these modernish temples has weird, abstract, non-representational decoration/symbols in them.
I think the sect has a thing for avoiding the representational art of the Catholics but has a need for decoration shunned by the plainer sects, and likes Islam’s take on geometric art. 
Except that John the Baptist was not one of the Twelve, so if the twelve stars represent the Twelve, then none of them represents the Baptist. On the other hand, if that symbol represents the Baptist, then what are the other eleven stars for?
The wider shot posted by in post 12 shows the stars displayed around a big crown. A crown with 12 stars appears in scripture, in Rev 12:1 (“a woman clothed with the sun, with the moon under her feet, and on her head a crown of 12 stars”). Any connection? On the other hand, since the church is the Church of Christ the King, there is a less apocalyptic explanation for the symbolism of the crown.
Punctuality and attendance.
These were my thoughts. Either Matthias, who was an alternate called up late or John with the tradition of not being martyred.
My own leaning would be toward Matthias.
I do not believe that any church would honor Judas, particularly with Matthias mentioned explicitly in Scripture.
Baptism would only make sense if there were twelve specific rites paralleling the seven sacraments of Catholicism. Since the Lutherans recognize some, not all, sacraments, (meaning far fewer than twelve), that would seem to dismiss Baptism–particlularly as the other eleven symbols are identical crosses, while there are not eleven identical, or even equal, rites.
It will be interesting if the church responds to the query.
The small crosses actually look like plus signs, all sides are equal. Maybe stylized stars? The squiggly thing may be a fish or serpent.
Mary was lying at the cross while the disciples stood around ?
Heh. Actually, though, that’s the Omega, which is the last letter of the Greek alphabet. It’s because God said in the Bible that he is the Alpha (beginning) and the Omega (end). Basically, it’s a symbol of God being eternal, or something like that. (It’s been a LOOOONG time since Catholic school)
I like the Viking longboat (obviously right for Lutherans, ya sure, yabetcha), but you would think they could have at least added the sail and maybe tried a little harder making the keel look at least like a keel.
Looking again, it looks like a serpent or snake. So, Satan, for Judas?
Seesh! :smack: I thought I’d reread the thread thoroughly, but evidently missed you clearly identifying the church.
Yeah, I think you got whooshed. The dude obviously knows what it is. They have an alpha on the other side, if anyone is curious.
Heh, I’ve been there! No biggie. We will only mock you forever now.
