Albert Barnes Commentary Acts 2:46

"And day by day, continuing stedfastly with one accord in the temple, and breaking bread at home, they took their food with gladness and singleness of heart," — Acts 2:46 (ASV)

With one accord. (Acts 2:1).

In the temple. This was the public place of worship, and the disciples were not inclined to leave the place where their fathers had worshipped God for so long. This does not mean that they were constantly in the temple, but only at the customary hours of prayer: at nine o'clock in the morning and at three in the afternoon.

And breaking bread. See Barnes on Acts 2:42.

From house to house. In the margin, it reads, "at home." The Syriac and Arabic versions also render it this way. The common interpretation, however, is that they did it in their various houses, sometimes in one and sometimes in another, as might be convenient. If it refers to their ordinary meals, then it means that they shared what they possessed. And the expression in this verse, did eat their meat, seems to imply that this refers to their common meals and not to the Lord's Supper.

Did eat their meat. This means they partook of their food. The word meat, in contemporary English, is often applied to flesh. However, in the Bible and in older English writings, it is applied to provisions of any kind. Here it means all kinds of sustenance—that which nourished them (Greek: trofhv)—and the use of this word proves that it does not refer to the Lord's Supper, for that ordinance is nowhere represented as designed for an ordinary meal or to nourish the body. (Compare to 1 Corinthians 11:33–34).

With gladness. This means with rejoicing. This is one of the effects of religion. It is far from gloom; it spreads joy in the mind and grants additional joy even in the participation of our ordinary pleasures.

Singleness of heart. This means with a sincere and pure heart. They were satisfied and thankful. They were not perplexed or anxious, nor were they overly concerned with luxurious living or aspiring after the vain objects of the people of the world. (2 Corinthians 1:12; Ephesians 6:5).
