As for the texts Col 2:16; Gal. 4:9-11; Rom. 14:5-6; these refer to ceremonial holy days, which we are not to keep today; however, the Sabbath is a creation ordinance which is part of God's moral law.

Note: I don't run down women who wear hats, I only criticise those who make it a term of communion.

BTW, the terms 'psalms', 'hymns' and 'songs' are all used in the Septuagint to describe psalms.

I think you are going too far in describing exclusive psalm-singers as pharisees; I myslef believe in total psalmody but recognise that others see it differently. Currently on my blog I am doing a series on psalmody, in response to something written by another brother which even he has enjoyed reading; see http://reformedcovenanter.wordpress.com/tag/worship/ for more information.

I am reading a good book at the minute called 'When Shall These Things Be' (edited by Keith Mathison, published by P&R) which refutes the damnable heresy of hyper-preterism. The contributors include both partial preterists and idealists. As a partial preterist myself I ABSOLUTELY HATE hyper-preterism, and anyone who believes it cannot be saved because he has denied the resurrection of the body (1 Cor. 15)

For anyone interested in the regulative principle I have just put a post on my blog 'Cain, Abel and the Regulative Principle' at http://reformedcovenanter.blogspot.com/

4. Note also(in relation to the first point)that the psalter took nearly 1000 years to be gathered together, Psalm 90 being the earliest,Psalm 126 the latest. No hymns were sung outside the psalter during intertestament period which there should've been if ex.psalmody is wrong

As Saintfield is in the island of Ireland, I think I am allowed to call myself Irish.
