I believe the etching has lots of connection to the church. Reminds me of the parable of the lost sheep from the Bible. These type of etchings/paintings were exceedingly popular in the early 1900's and continue to be so today.
The Parable of the Lost Sheep is a parable told by Jesus in the New Testament of the Christian Bible, Matthew 18:12-14 (12How think ye? if a man have a hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and goeth into the mountains, and seeketh that which is gone astray? 13And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep, than of the ninety and nine which went not astray.) and Luke 15:3-7 (107. Jesus said, "The (Father's) kingdom is like a shepherd who had a hundred sheep. One of them, the largest, went astray. He left the ninety-nine and looked for the one until he found it. After he had toiled, he said to the sheep, 'I love you more than the ninety - nine.'") . It is also found in the Gospel of Thomas 107.
The picture may be from the church or a parishioner from the church etched it....or gave it to him.
