Such was the popularity of the Newbattle Communion Sacrament that adjoining Parishes closed on such Sundays and the occasion became known as a Holy Fair. The principle was adopted by local Parishes, resulting in such events as the Dalkeith Fair. The Newbattle Fair became known as the Newbattle Sacrament, a Day of Freedom. The Rev Aird did many things for the Parish, such as implementing Knox's ideal for a Settled School in every Parish, the first Parish School being built in the area close to the site of the present church.
