In Acts 2, we are told of the early church: “They devoted themselves to the apostles’ teaching and fellowship, to the breaking of the bread and the prayers. And they sold their possessions and goods and distributed to all, as any had need.”
Richard Paquier comments on the interrelationship here between the church’s adherence to the apostles’ teaching, the church’s common prayers and partaking of the Lord’s Supper, and the church’s care for the poor:
These three aspects of the common life of the first believers, even if clearly distinguished from each other, are nevertheless very intimately connected.
The breaking of bread and the prayers, therefore, include necessarily the teaching of the faith and the declaration of the word; worship is done in a brotherly agape [love] and includes perhaps already an offering for the poor (cf. I Cor. 16:1-2).
It is in prayer and in the fraternal and sacramental communion that the congregation nourishes its life in Christ and draws its strength in order to witness to the outside: it is there as well that the impetus is given to those charged with the dedication of themselves to their less fortunate brethren.
When worship is neglected or degenerates, witness to the faith and charitable works dry up; and inversely, a church that is no longer missionary within its environment and gives only parsimoniously to help the poor, proves that the worship it celebrates is merely an empty formality (Dynamics of Worship, xviii-xix).
