Acts 2:42

42 And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.
Commentaries
Didacheon Acts 2:42AD 100
But every Lord's day do ye gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure. But let no one that is at variance with his fellow come together with you, until they be reconciled, that your sacrifice may not be profaned. For this is that which was spoken by the Lord: In every place and time offer to me a pure sacrifice; for I am a great King, saith the Lord, and my name is wonderful among the nations.
John Chrysostomon Acts 2:42AD 407
"And they continued steadfastly and with one accord in the Apostles' doctrine and fellowship." Here are two virtues, perseverance and concord. "In the Apostles' doctrine," he says: for they again taught them; "and fellowship, and in breaking of bread, and in prayer." All in common, all with perseverance.
John Chrysostomon Acts 2:42AD 407
"And they continued" it is written, "steadfastly in the doctrine" (or, "teaching") "of the Apostles": for it was not for one day, no nor for two or three days that they were under teaching as being persons who had gone over to a different course of life. "And they continued with one accord in the Apostles' doctrine," etc. The expression is not "together," but "with one accord," ("and daily," he says afterwards, "they were continuing with one accord in the temple,") i.e. with one soul.
John Chrysostomon Acts 2:42AD 407
And here again in his conciseness, he does not relate the teaching given; for as young children, the Apostles nourished them with spiritual food.
Cassiodoruson Acts 2:42AD 585
"And they were persevering in the doctrine of the apostles," etc. As those who had converted continued devoutly in the doctrine that they had embraced, and as the apostles frequently performed great miracles, the fear of the Lord and the number of the faithful people increased daily. There was great concord among the believers, such that everyone would sell their own possessions and a brother would unfailingly be provided with whatever he stood in need of. Great also was their devotion to meeting in the temple. They would, too, take their food in simplicity of heart and with thanksgiving. That is why the Lord, favorably inclined towards them, always increased their number. Once, when Peter and John went up to the temple for prayer, they took the hand of a man who had been lame from his mother's womb and made him walk with firm steps. The people, seeing this, were filled with inexpressible wonder, and their eagerness to see more grew greater and greater, with vehement devotion.
CS Lewison Acts 2:42AD 1963
The only rite which we know to have been instituted by Our Lord Himself is the Holy Communion ('Do this in remembrance of me' - 'If you do not eat the flesh of the Son of Man and drink His blood, ye have no life in you'). This is an order and must be obeyed. The other services are, I take it, traditional and might lawfully be altered. But the New Testament does not envisage solitary religion: some kind of regular assembly for worship and instruction is everywhere taken for granted in the Epistles. So we must be regular practising members of the Church.

Of course we differ in temperament. Some (like you - and me) find it more natural to approach God in solitude: but we must go to church as well. Others find it easier to approach Him through the services: but they must practice private prayer and reading as well. For the Church is not a human society of people united by their natural affinities but the Body of Christ in which all members however different (and He rejoices in their differences and by no means wishes to iron them out) must share the common life, complementing and helping and receiving one another precisely by their differences. (Re-read 1st Corinthians cap 12 and meditate on it. The word translated members would perhaps be better translated organs).
