Does anyone know what this could be

Hello from australia. Both my parents are from the Netherlands and migrated here in the 60s/70s. I was visiting my dad today and found this. He has no idea where it came from or what it means.

I’m assuming it’s a puzzle or riddle? Most likely something catholic related being it’s probably from my Oma.

Would love any input. Thanks
