In the same year, 1675, Molinos published his most famous work, the "Spiritual Guide". The initial Spanish edition was quickly followed by an Italian translation entitled "Guida spirituale, che disinvolge l'anima e la conduce per l'interior camino all' acquisito della perfetta contemplazione e del ricco tesoro della pace interiore" (Spiritual Guide, which releases the soul and conducts it through the interior path to acquire the perfect contemplation and rich treasure of interior peace). The work was published with the usual approval from the ecclesiastical authorities – the book received the imprimatur from the Dominican Raimondo Capizucchi, the pope’s own theologian, and the book opened with approbations by clergy of the Trinitarian, Franciscan, Carmelite, Capuchin and Jesuit orders. This was followed soon after in 1675 by a brief "Trattato della cotidiana communione" ("Brief Treatise on Daily Communion"), in which Molinos argued that those who wished to receive the Eucharist daily should not be denied by their confessor, so long as they were in a state of grace. Again, this work was approved by the censors of several orders.
