I think it's worth mentioning that the Genevan Psalter itself was one of the Psalters the English had available and found problematic,
it being published in English in 1632.
Thank you SO MUCH for that link! I just got done reading the preface, which noted the need for English speakers worshipping with the French Huguenots or Dutch Reformed to have the Genevan Psalter in English so they could sing alongside the French and Dutch, and thought of my Korean mother-in-law who can't understand anything I say in English from the pulpit but will sing along with the Genevan Psalter in Korean, and also recite in Korean the Lord's Prayer and certain other parts of the historic Waldensian liturgy, which is itself based on Calvin's Strasbourg liturgy. I'm sitting in a hallway of our county courthouse outside a closed session of our county commission, and quietly sung a few verses of Psalm 2 from that four-centuries-old English translation of the Genevan Psalter.
Maybe it's my ethnic Italian blood coming out, but I think we in the Reformed world have lost a great deal by forgetting that in the Reformation era of the 1500s and 1600s, and well into the 1700s and even 1800s, a Reformed person could travel to a Reformed church in most of Continental Europe and sing from a common Psalter, use a similar liturgy, and after the Heidelberg Catechism started to be widely used, often though not always have the same catechism.
That's something we haven't ever really had in the English-speaking world. Many of my Catholic friends like to point out that when they go a traditional Catholic Mass almost anywhere in the world, they will see pretty much the same thing, whereas if they visit a Protestant church, they'll have no idea what to expect, even in the same theological tradition or (often) even in the same denomination.
They have a point today. They would not have had a point four centuries ago when most Reformed people had a shared idea of what worship, singing, and catechesis should look like.
The main reason that no Psalter ever achieved universal acceptance was simply that the civil authorities never endorsed one. Officially, Anglican services endorsed, not singing the psalms, but reciting them from the Book of Common Prayer, but unofficially, the bishops often turned a blind eye to low church congregations singing the psalms, which meant that a large number of Psalters, none with official endorsement, proliferated for the use of low church anglicans, presbyterians, and congregationalists in England. Ainsworth, Patrick, Ford, Sternhold, Baxter, Playford, Barton, Smythe, the translator of the Genevan Psalter, and many others all took their shot at making an English Psalter.
The only places where a single Psalter was widely accepted were places where ecclesiastical authorities adopted one, such as in New England and Scotland.
I surely agree with you that it's hard for modern Americans to understand the level of importance of state authority in enforcing conformity among the Reformed in most of Europe, and you have a point.
But I do think there are other factors at play.
Nobody was forcing the French Huguenots, or the Italian Waldensians, or the Dutch Reformed, or the Hungarian Reformed, to use the Genevan Psalter.
The Genevan consistory had spiritual authority only in Geneva and its attendant villages. The city council's authority was also geographically limited.
The French Huguenots and Italian Waldensians were often under harassment or even open persecution by the civil authorities. The Dutch synods and civil authorities and the Hungarian synods and civil authorities adopted the Genevan Psalter because they were persuaded of its value, not because the Genevan consistory or city council had some sort of authority over them.
The Scots and English were outliers in refusing to adopt the Genevan Psalter, despite many of the English and the Scots having worshipped in Geneva itself during periods of exile.
I think there were other factors at play beyond simple lack of ecclesiastical enforcement mechanisms.
