Sunday Worship

The following is from the Letters of John Newton (pastor and author of the text "Amazing Grace"). It was written to his church in 1768. I found it interesting and provocative. Any thoughts? Is he "out to lunch" or does he make a valid point?

"If you are one of those who do not wholly neglect the public worship of God—but accustom yourself to attend only once on Sundays, give me leave to ask you, or rather to desire that you would ask your own conscience, whether you have sufficient excuse for not attending twice? I know the circumstances of many families, such as sickness, young children, etc. will necessarily confine some people at home. But a due allowance for these impediments, will by no means account for the great difference between our congregations in the morning and in the afternoon of the same day.

Now, if you have not a lawful hindrance to plead, consider whether the same reasons that require your presence at the public worship once, are not equally strong for your being there both parts of the day. Why do you go at all? Is it not to join with others in paying homage to the great God? But by doing this once only, where opportunity and the example of others invite you twice—you contradict yourself, and act as if you thought it was sometimes your duty to join in worship, and sometimes not worth your while. Or, do you go with a hope of receiving good for your souls? Why then should you at any time be willing to stay away? Perhaps the opportunity you miss might have been made peculiarly useful to you. At least the Lord may justly punish your frequent neglect, by withholding His blessing when you do attend. And this may be one reason why you have attended morning worship so long—yet to so little purpose."
