A dialogue on the Christian sacraments : wherein the nature and import of an attendance on them are enquired into, from the Scriptures; the Protestant churches, and divines are consulted; and the singular notions of some on these heads, with their reasonings in support of them, are examined. : The whole being done with a view to furnish a scriptural answer to this very serious and important question, viz. What are the qualifications that are necessary, or which God requires in any person, in order to his attendance on the sacraments of the New Testament? : [One line from Isaiah].
