The Office of Deacon Was Created for the Purpose of Handling the Benevolence Ministry

The Biblical account is quite clear on the founding of the deaconship and nowhere does Scripture repeal the original purpose:

“NOW ABOUT this time, when the number of the disciples was greatly increasing, complaint was made by the Hellenists (the Greek-speaking Jews) against the [native] Hebrews because their widows were being overlooked and neglected in the daily ministration (distribution of relief). So the Twelve [apostles] convened the multitude of the disciples and said, ‘It is not seemly or desirable or right that we should have to give up or neglect [preaching] the Word of God in order to attend to serving at tables and superintending the distribution of food. Therefore select out from among yourselves, brethren, seven men of good and attested character a nd repute, full of the [Holy] Spirit and wisdom, whom we may assign to look after this business and duty.’” Acts 6:1-3 (Amplified)

The Office of Deacon Was Established to Free the Apostles (who functioned as the first pastors) to Pray and to Prepare to Minister the Word
The Apostles, in dealing with the benevolence ministry problem at the Jerusalem church, told the congregation that,

“It is not desirable that we should leave the word of God and serve tables. Therefore, brethren, seek out from among you seven men of good reputation, full of the Holy Spirit and wisdom, whom we may appoint over this business; but we will give ourselves continually to prayer and to the ministry of the word.” Acts 6:2-4 (NKJV) 

2 Corinthians 3:6 – Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
