Whether any Roman Catholic source is quoted about how the theology of Palamas should be understood in the West - I doubt that any is - there are overwhelming reasons for quoting Roman Catholic sources for how the theology of Palamas is understood in the West.  Eastern Orthodox scholars are not the only scholars who study Palamism.  Sources quoted for the Catholic Church article include Eastern Orthodox, Jews, Anglicans ...  And rightly so.  It would be nonsense to exclude them just for not being Catholic.
