Indeed. Arab Christians fresh off the boat might want to explore local churches. Being unfamiliar with the non-traditional layout of many American churches, they can be forgiven for wanting a map. Give them what they want, hand them a guest card to fill out, then call them and schedule a home visit. If they are honest, you may gain a family or two in your congregation. If they are lying, you will know as soon as you conduct the follow-up, and you can react accordingly.
I trust the sense of those observing the blokes more than that.
It’s not exactly rocket science.
Arabs seriously interested in church for positive reasons know how to seek out information honorably. They are far from total idiots about everything.
Wouldn’t they be interested first in the beliefs and doctrine of the church, what programs for teens/children/other age groups? The kinds of questions stated by the OP divorced from these kinds of questions would seem fishy to me, if they are merely considering joining the church. Wouldn’t they want to have a different conversation with a member other than just these strange questions, strange coming from a potential member?
BS. Any Arab Christian interested in church services (or anyone interested thusly) would search out people to talk to and ask when services are, get fliers or schedules and so on.
This is obviously suspicious behavior. Odd that you don’t see that.
