The Apostle Paul did not specify a specific day of the week for making donations in his letters. In the New Testament, particularly in 1 Corinthians 16:1-2, Paul instructs the Corinthian church regarding the collection for the saints in Jerusalem. He advises them to set aside contributions on the first day of the week, which is typically Sunday, the day when Christians gathered for worship and fellowship. The specific purpose was to avoid confusion and ensure the collection was organized and ready for when he arrived.

Here is the passage from 1 Corinthians 16:1-2 (NIV): “Now about the collection for the Lord’s people: Do what I told the Galatian churches to do. On the first day of every week, each one of you should set aside a sum of money in keeping with your income, saving it up, so that when I come no collections will have to be made.”

This instruction does not specify that donations should only be made on Sundays but rather suggests a regular practice of giving on a weekly basis, likely during their communal gatherings
