It was written to the brethren. But still, I see that as not a command to use the church treasury for benevolence for those outside of Christ. The treasury can be used for benevolence to only those who are of the faith. However if I see someone in need and I am able, I can use my personal funds to extend help to him. That is in keeping with the Word. I see no scriptures for the Lord's church that authorizes the use of the treasury for food pantries or orphanages or to fund colleges.
