The short version is that Emmanuel Lutheran Church will not hold any church services, or events from now until March 31. After that date is still to be determined. Small council meetings of less than 10 people are still able to meet if they so decide.
The following is the official statement from the governor's office.
“Pursuant to Iowa Code § 135.144 (3), and in conjunction with the Iowa Department of Public Health, unless otherwise modified by subsequent proclamation or order of the Iowa Department of Public Health, I hereby order that effective Noon today, March 17, 2020, and continuing until 11:59 p.m. on March 31, 2020:
.... E. Mass Gathering: Social, community, spiritual, religious, recreational, leisure, and sporting gatherings and events of more than 10 people are hereby prohibited at all locations and venues, including but not limited to parades, festivals, conventions, and fundraisers."
So we will follow the law, and keep you informed of any updates as this is a constantly changing situation.
