True harmony

Science and Health with Key to the Scriptures
by Mary Baker Eddy, p. 255:3–6
“Let there be light,” is the perpetual demand of Truth and Love, changing chaos into order and discord into the music of the spheres.

The Christian Science Hymnal, No.  196:2
Let all that now unites us
More sweet and lasting prove,
A closer bond of union,
​In a blest land of love.

The Bible
(I Corinthians 14:7, 26)
And even things without life giving sound, whether pipe or harp,
except they give a distinction in the sounds,
How shall it be known what is piped or harped? ...

How is it then, brethren? when ye come together,
every one of you hath a psalm, hath a doctrine,
hath a tongue, hath a revelation,
hath an interpretation.
Let all things be done unto edifying.
