No stained glass windows? No lofty ceiling?
How about lifelike statues of Jesus (baby in Mary's arms, adult), large main crucifix?
When my husband and I lived in the Valley (California) I attended just such an uninspiring place of worship. In Saudi Arabia we used a multipurpose room and we glad to have the space to worship AND a priest.
NO excuse for the USA--just terrible IMHO.
TSK! I have another reason for loving my older, urban church.
We have all those things, but it's still not a "church" by regulation.
