A Catholic tradesmen’s guild is an association of men in the skilled trades who, under the social teaching of the Church, unite their professional, fraternal, and spiritual lives. They seek holiness through their work, mutual assistance through brotherhood, and the flourishing of their families, trades, parishes, and communities.
Pope Leo XIII wrote in 1884 that he greatly wished “that these guilds may be generally restored.” He named the purpose plainly: to help the honest workman, to protect and guard his children and family, and to promote in them piety, Christian knowledge, and a moral life.
That is the difference between a guild and a referral network. A network gets you work. A guild also gets you to Mass, shows up when your wife is in the hospital, and hands a young man a trade.
One of our carpenters put it this way at a formation meeting: before the Guild, he had customers and he had a parish, and the two never met. Now they do.
