Reliable sources tell Pray Tell that the publication of the Leccionario for Spanish-speaking communities of the United States has been postponed by the USCCB.The problem is mostly with the psalms.
The Leccionario for the USA was approved by the Holy See, with plans to have it out by next Ash Wednesday (2015). US bishops planned to take readings from Mexico and psalm from Spain, to have consistency with other Spanish-speaking places. But the psalms (from Spain) somehow got altered in their path to the US-approved book. And then Spain further revised its translation, making the US version both erroneous and obsolete.
So the Decree for Publication was revoked in early September. Difficulties will have to be ironed out, and the Holy See will have to clarify some things. By when? Anybody’s guess.
