I would find this feature very valuable, but I certainly have concerns over abuse, so I sympathize with those who have down-voted this topic.  

That being said, some benefits I see are:

Looking up addresses when I'm away from home and I don't have a church directory with me.

Those who put together our physical local church directory could use it as a mechanism for getting the latest addresses.

From a sound bench perspective, it would be nice to retrieve spelling of names of brothers from other congregations who have prayers at our church.

Just a few thoughts:  

Could access to the directory require a login?

Could we assign a local church "admin" that would be responsible for approving/granting access for their respective church members?

Could there be levels of access that each individual/family could grant for their information?

Level 1: Name only (Default), 

Level 2: Name & Address, 

Level 3: Name, Address, Phone, Email

Perhaps we could limit access of pieces of our information to our own congregation?  Ex. Anyone can see my name, but only my local congregation can see my name/address.

Could there be a way to "Report Abuse" if someone felt their address was misused.

If this were to move forward, I would perhaps defer adding the ability to download of lists of contacts until we saw how people respond to the address book.

Could downloading of lists be logged/recorded and could these logs be accessed by the local church admin?

I know security is a bit complex, these are just some questions/thoughts I've had over the years on this topic.

Funeral sermon uploads are up to each respective church.  I would reach out to Peoria and request that they upload their funeral services or perhaps someone from Peoria may read this.  :)

Good to know, thank you.  However, the congregation filters are missing.  It would be nice if it was simply populated with the congregation in the URL, but we had the option to switch.
