Romans 16:3-5a  Greet Priscilla and Aquila my helpers in Christ Jesus: Who have for my life laid down their own necks: unto whom not only I give thanks, but also all the churches of the Gentiles.  Likewise greet the church that is in their house. . .
 
I can think of no greater praise for a believing couple than to be likened to Aquila and Priscilla.  Here we see that this believing couple were helpers of the Apostle Paul and that they had even put their lives on the line for him.  We also see that they ran a fellowship in their home in Rome.

Acts 18:1-3 After these things Paul departed from Athens, and came Corinth; And found a certain Jew named Aquila born in Pontus, lately come from Italy, with his wife Priscilla; (because that Claudius had commanded all Jews to depart from Rome:) and came unto them. And because he was of the same craft, he abode with them and wrought: for by their occupation they were tentmakers.
 
When Paul first witnessed to Aquila and Priscilla they were in Corinth.  They had left Rome because the government had commanded all Jews to leave.  Later on, as we saw above, they returned to Rome with the Word of God and ran a fellowship in their home.  In Corinth they got born again and lived and worked with the Apostle Paul.  In the Bible lands "tentmakers" was an occupation for women.  The corresponding occupation for men was to make saddles.  Paul, Aquila, and Priscilla worked together in this occupation as Paul spoke the Word in Corinth.  Aquila and Priscilla learned God's Word from Paul as they worked side by side.

Acts 18:18-19 And Paul after this tarried there yet  a good while, and then took his leave of the brethren, and sailed thence into Syria, and with him Priscilla and Aquila . . . And he came to Ephesus and left them there: . . .

Aquila and Priscilla traveled with Paul and stayed in Ephesus.  While in Ephesus do you know what Aquila and Priscilla did?  They ran a fellowship in their home.

I Corinthians 16:19 The churches of Asia salute you.   Aquila and Priscilla salute you much in the Lord with the church that is in their house.

and they spoke God's Word . . .

Acts 18:24-26 And a certain Jew named Apollos, born at Alexandria, an eloquent man, and mighty in the scriptures, came to Ephesus.  This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John.  And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly.

Aquila and Priscilla heard Apollos speak the Word.  Apollos was an educated, eloquent man trained at Alexandria the great Greek learning center.  He was bold and "mighty in the scriptures," yet he did not know the Word as well as this simple believing couple that had worked with and learned the Word from the Apostle Paul.  Aquila and Priscilla took Apollos home and taught him God's Word.  Now that is fellowship in the home.  What a great example of a believing couple.

II Timothy 4:19 Salute Prisca and Aquila, and the household of Onesiphorus.

At the end of the Apostle Paul's life Aquila and Priscilla were still standing on God's Word.

Acts 5:42 And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ.

As we saw with Aquila and Priscilla the first century believers met and spoke God's Word in homes.  The temple area was a public meeting place where the believers witnessed and spoke God's Word.  In every house the believers taught the Word and had fellowship with other believers.

Acts 20:20 And how I kept back nothing that was profitable unto you, but have shewed you, and have taught you publickly, and from house to house.

The believers met and learned God's Word in the home.  Here are some of the homes:

• Acts 9:11-17 - the house of Judas was where Paul received his sight.
• Acts 10:5-6 - the house of Simon the tanner was where Peter was called to the Gentiles.
• Acts 12:12-17 - the house of Mary was where believers met and prayed for Peter to be release from jail and was where Peter went when God got him out.
• Acts 16:40 - the house of Lydia was the first house where believers met in Philippi.
• Acts 17:5 - the house of Jason was the first house where believers met in Thessalonica.
• Acts 18:7 - the house of Justus in Corinth (and the house of Aquila & Priscilla).
• Act 21:8 - the house of Philip the Evangelist in Caesarea.
• Acts 28:30 - Paul's own rented house in Rome.

The Greek word for church is the word ekklesia.  Ekklesia means assembly or called out.  The believers assembled in the home to fellowship one with another, to pray, and to learn God's Word.

Colossians 4:15 - Salute the brethren which are in Laodicea and Nymphas, and the church which is in his house.

In the epistles believers are called saints.  The word for saint is the Greek word hagion.  It means holy.  Only those to whom God has given holy spirit can rightfully be called saints.  We are God's holy ones because we have holy spirit from God abiding within us.

Ephesians 2: 19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;

If you are a fellowcitizen with an American then you are an American.  If you are a fellowcitizen with the saints you are a saint.

Romans 1:8 First, I thank my God through Jesus Christ for you all, that your faith [believing] is spoken of throughout the whole world.

This is my prayer as well.  I thank God for you saints like Aquila and Priscilla that run fellowships in your homes and hold fast the Word of God.  I thank God that your believing is spoken of throughout the whole world wide web and more importantly in your own home.

I Corinthians 1:4 I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ;
