According to
Diarmaid Ó Muirithe, "Ferns was without a regular Bishop between 1651 and 1684. Bishop
Nicholas French had left Ireland to seek the help of the
Duke of Lorraine, but because of the enmity of the
Duke of Ormonde he was refused permission to return even after the
restoration of
Charles II. In 1668, French invited his first cousin Luke Wadding to return to Wexford to represent him as
Vicar General of Ferns. He appointed him parish priest of
New Ross." Due to the sympathies of the King and his suspension of all anti-Catholic
religious persecution through the
Declaration of the Indulgence, there was a general relaxation and the
Tridentine Mass increasingly moved from outdoor
Mass rocks () to thatched "Mass houses" (, lit. ‘Mass Cabin’). Writing in 1668,
Janvin de Rochefort commented, "Even in Dublin more than twenty houses where Mass is secretly said, and in about a thousand places, subterranean vaults and retired spots in the woods". At the same time, the whole Catholic Church in Ireland had been devastated and Fr. Wadding had to rebuild the Diocese from the ground up. With the assistance of Irish
Jesuits Stephen Gelosse and Stephen Rice, he founded a
Catholic school in New Ross for 120 young boys. After grudgingly accepting a promotion to
Coadjutor Bishop of Ferns with right of succession in 1673, Wadding moved to
Wexford, while indefinitely delaying his episcopal consecration with Bishop French's approval. He asked, however, to be sent from abroad a
pectoral cross, a
mitre, a
crozier, some vestments, and everything else necessary for saying a
Pontifical High Mass, "for nothing of the sort can be had here". According to Barry Crosbie, the fact that Wadding was lodged in Wexford and protected by the highly influential
Anglo-Irish and Protestant Wiseman family made it possible for him to smuggle "popular contemporary books of doctrine and devotion, catechisms, and prayerbooks", from
Catholic Europe into his Diocese. Furthermore, "In an effort to encourage and increase literacy and religious devotion, he then distributed these items among his friends and relatives. One of his most difficult tasks was to establish some much needed Church structures, both physical and organisational. The existing baptismal and marriage registers for the Catholic parish of Wexford Town, begun in 1672 by Wadding, are among the earliest known documents of their kind in Ireland." In 1674, Wadding began building a public Mass-house inside the walls of Wexford, which only his friendships with the Anglo-Irish and Protestant elite of the town allowed him to get away with. The project took him 12 years to complete and cost a total of £53.14s.9d. According to
Diarmaid Ó Muirithe, "He gives details of its glazing, ceiling,
thatching, etc., in his account book, and mentions that he had to remove a great heap of dung from the site before he could lay the foundations of his little chapel. It is evident that he maintained as best he could the dignity of his office and he had a good quantity of chalices, ciboria, pixes, silver cruets, and silver and pewter oil-stocks. He had a plentiful supply of vestments." During the
show trials and
anti-Catholic hysteria concocted by
Titus Oates and Lord Shaftesbury, Wadding was arrested for violating the law commanding all Catholic bishops, vicars general, and regular clergy to leave Ireland by 20 November 1678. In response, Wadding explained that he not a bishop and had creased to be a vicar general following the recent death of Bishop French in Ghent. Somehow, he was able to remain in Wexford and avoid deportation. ==Bishop==
