A welcome speech for Mother's Day that is appropriate for church should create anticipation in the audience about the upcoming service. The speech should welcome all the congregants, especially mothers and other important guests.
According to WriteOutLoud.com, a welcome speech gives a brief introduction of the occasion, in this case Mother's Day. The speech starts out with a quote or words of encouragement that center the audience on the topic of Mother's Day. After acknowledging all mothers and important guests, the speaker moves to key points. These can be qualities of good mothers, reasons to appreciate mothers or any other appropriate remarks. Each point should be supported with a quote, an example or an anecdote. At the end of the speech, the speaker thanks the audience and hands over the stage to the next speaker by introducing him.
Because this speech is specifically for church, religious quotes about motherhood are appropriate. For instance, Genesis 3:20 talks about Adam calling for Eve "because she was the mother of all living." However, the quotes do not need to be from the Bible. Abraham Lincoln said of his mother, "I cannot tell you how much I owe to the solemn word of my good mother." Alternatively, words of poetry add interest. "The Hand That Rocks the Cradle" by William Ross Wallace includes inspirational words about motherhood.
