Most of the deck officers were, unsurprisingly, Church of England - e.g. Boxhall, Moody and Lowe. Within that there were some distinctions - Moody's family, for example, were associated with the High Church. His grandfather was instrumental in the construction of the beautiful church of St Martins on the Hill in Scarborough, which attracted some controversy due to the Pre-Raphaelite ornamentation. The Oxford Movement of the mid-Victorian age had seen a revival of ritualism and decoration that was seen in some circles as smacking of Roman Catholicism, and it is certainly evidant in St Martins. The accusation of closet 'Papism' was levelled in some sections by those opposed to the church's design. Although James Moody almost certainly never attended the church of St Augustine's in Grimsby (it was only consecrated at the beginning of 1912), his family were also closely associated with this church and parish. A Requiem Service for the repose of his soul was held here in April 1912. Visiting the St Augustines, as with services I've attended in St Martins, I was struck by the similarity in ornamentation and order of the service to the Roman Catholic churches I'm more familiar with - certainly more so than with the Low Church services I've attended with a relative of another Titanic officers. It is interesting that one member of the Moody family later converted to Catholicism after an experience during WWI.
Harold Lowe's family had Wesleyian influences in previous generations (there's a wonderful story, possibly apocryphal, concerning how an ancestor of his saved John Wesley from being stoned). Lowe himself was a profound believer and served as a church warden in later life.
Henry Wilde was married in a Welsh Calvinist Church in Wales - possibly the influence of his wife and her Welsh family.
