Bible Questions and Answers

A visitor writes,

"I am an ex Christadelphian I disfellowship the religious system I was involves with because of their spiritual adulteries with music. Where is your biblical mandate to congregational musical worship under the new covenant, the law of Moses, King David?"

I can find no commandment in the New Testament forbidding the use of music in the worship of God.
On the contrary, music has always been used in worship:
1 Chronicles 13:8  And David and all Israel played before God with all their might, and with singing, and with harps, and with psalteries, and with timbrels, and with cymbals, and with trumpets.
Nehemiah 12:27 Now at the dedication of the wall of Jerusalem they sought out the Levites in all their places, to bring them to Jerusalem to celebrate the dedication with gladness, both with thanksgivings and singing, with cymbals and stringed instruments and harps.
Psalms 33:2  Praise the LORD with the harp; Make melody to Him with an instrument of ten strings.
Psalms 92:3  On an instrument of ten strings, On the lute, And on the harp, With harmonious sound.
Psalms 98:5  Sing to the LORD with the harp, With the harp and the sound of a psalm,
Psalms 100:2  Serve the LORD with gladness; Come before His presence with singing..
Isaiah 51:11  So the ransomed of the LORD shall return, And come to Zion with singing, With everlasting joy on their heads. They shall obtain joy and gladness; Sorrow and sighing shall flee away.
Isaiah 54:1 "Sing, O barren, You who have not borne! Break forth into singing, and cry aloud, You who have not laboured with child! For more are the children of the desolate Than the children of the married woman," says the LORD.
Matthew 26:30  And when they had sung a hymn, they went out to the Mount of Olives.
Mark 14:26  And when they had sung a hymn, they went out to the Mount of Olives.
Ephesians 5:19  speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord,
Colossians 3:16  Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
Perhaps you would like to explain in what way the use of music in worship constitutes ‘spiritual adultery’.
God bless,
