Just a friendly reminder-both before and during the Divine Service, talking in the church itself should be kept to an absolute minimum. Many people use the time before the service to meditate on the Word of God and prepare for worship and the reception of Holy Communion. Extraneous conversations should not distract from this. And during the service itself, even during the offering or the Lord's Supper, indiscriminate talking should not take place. For we are in the very presence of the Lord, taking part in His holy liturgy. The words we speak are the ones He Himself has given us. Outside of that, the words of Habakkuk 2:20 apply: "But the LORD is in His holy temple. Let all the earth keep silence before Him." The hymn puts it this way:

Let all mortal flesh keep silence
And with fear and trembling stand;
Ponder nothing earthly-minded,
For with blessing in his hand
Christ our God to earth descending
Comes our homage to demand. (LW, 241)

Therefore, before the service please enjoy conversations with one another in the narthex and not in the pews or the back of the church. Of course, following the service, after you have received the benediction of the Lord, feel free to greet and speak with one another as you depart from the Lord's house, be it in the church itself or in the Parish Hall afterwards. We do not want to become a "cold" congregation, but one that shows the highest honor to the Lord and His Word and Sacraments. We can be both reverent and friendly at the same time!
