A Spanish language translation of The Second Comforter: Conversing With the Lord Through the Veil is now available in print and should be available next week on Kindle.
The Spanish title is El Segundo Consolador: Conversando con El Senor a traves del Velo
This is the same book as The Second Comforter, translated into Spanish by a volunteer committee. The material in the book was sound LDS doctrine/teaching when originally written. Since that time the teaching has been denounced by the LDS Church, and therefore it is important as a point of contrast between what was taught for over a century-and-a-half by the LDS Church and what they have rapidly abandoned in only the last decade.
If you know of any Spanish readers who would be interested in this important teaching, they may want to read this volume. Although the institution has removed it from their body of teaching, the book teaches truth about the Gospel of Christ.
