En esta obra, Pere Gual defiende la Immaculada Concepción de la Virgen María, que había sido declarada dogma de fe por el Papa Pío IX en 1854. El autor se enfrenta a un escritor anónimo que había cuestionado la validez de este dogma. Una obra que está en línea con otros escritos apologéticos católicos de la época.
