In view of its charisma, the spirituality of Yahweh the Saviour Fraternity has a clear praying and apostolic character. It was born of the Holy Spirit who was poured out upon our hearts of servants of Yahweh the Saviour and of the filial adoption He destined us to himself through Jesus Christ. Our spirituality is cultivated through the Gifts of God bestowed upon us and extended to our brothers through us. So, our consecration, praying life, community life and apostolic life are completely in tune all the time.
     Our spirituality is specifically and fully engaged in reaching the sanctity of life for our members, in every community branch, and for whoever may God put in our way. The Yahwist spirituality is, therefore, a charismatic or renewed spirituality. It has been designed based on some foundations through which all life and actions of the Institute are guided, making it a charismatic Institute:

     1º. We believe that the spiritual gifts as mentioned in the Holy Scriptures particularly in I Cor 12, 13 and 14 and the fruits of the Holy Spirit, particularly in Gal 5, 22-25 may take place even today for whoever who claims and waits for by means of the same Holy Spirit, for a new Pentecost in their Christian lives;

     2º. We believe and rely more on the direct action and anointing of the Holy Spirit than in the capacity and sophisticated techniques of men;

     3º. We believe and rely on the divine inspirations, loving the Word of God contained in the Holy Bible and having it as a companion and studying it night and day;

     4º. We wish to live in perfect obedience, as Christ was obedient to death even death on a cross, to God the Father and consequently to the Holy Church and its Hierarchy;

     5º. We wish to obey our Lord and our Church, by testifying the Gospel with no fear or pusillanimity;

     6º. We try to live the mysteries of God the Father and Christ in the Holy Spirit, by means of the Sacraments frequently received, by attending the Holy Sacrifice of the Mass and the Sacrament of Penance, in prayer, by frequent immolations and fastings, by taking care of ill people and by making other acts of christian mercy, through the personal testimony of God´s graces in our lives in order to encourage and build up the people of God and bring up to date those acts of the Early Church christians;

     7º. We dedicate diligently to the prayers and hymns and songs of praise to God so as to declare all His wonderful deeds, making it through our souls and bodies, raising our arms to Him, the Creator of our beings. We really don´t care with the reproachful eyes of the world for which we are nothing but alienated people; the world will never be aware what kind of wine we are inebriated of;

     8º. We wish to live in the deepness of the Holy Spirit, in contemplative prayer, without being too much disturbed with the haste of the world which drives away our attention, with the social life which misguides the way to conversion of life and do not proclaim Jesus Christ and His Gospel;

     9º. We would rather be either a mystic or a recluse than a vineyard servant who is not able to stop in order to choose the better part that will not be taken from us;

     10º. We believe to save more souls to Heaven through the apostolate and prayer - the soul of any apostolate - than through working relying more upon our own ideas and strength;

     11º. We believe and are sure that the Early Church Pentecost, when miracles, healings and wonders took place is in fact happening today in our lives and in our times; only those who never stop to perceive the "signs of end times" as warned by Jesus Christ fail to experience them;

     12º. We believe and declare openly our full adherence to the Divine Providence and reproach any and all coincidences and accidental occurrences that may take place at any moment of our lives and banish from our lives any force or power not solely and directly oriented towards the power of God and the action of the Holy Spirit because "Can any of you by worrying add a single moment to your life-span" (Matt 6,27). In fact, we should not worry about anything, because "Even all the hairs of your head are counted; yet not one of them falls to the ground without your Father´s knowledge (Matt 10,29-30). "Instead, seek His Kingdom and these other things will be given you besides" (Luke 12,31).

     13º. We believe and wait for the promise of hope given by the Risen Christ that we would be baptized with the Holy Spirit, both ourselves and those who waited for the fulfillment of the Father´s promises that we have heard from His mouth, and manifested to many both yesterday and today, by pouring out on Pentecost His Paraclet on all these who devoted themselves with one accord to prayer together with some women, and Mary, the mother of Jesus.

     14º. We believe and accept humbly and with a cordial interest the particular revelations that God is giving today, as He has always given throughout the history of the Church and the Saints, to the humble of heart. Jesus rejoiced in the Holy Spirit, and said "I give you praise, Father, Lord of heaven and earth, for although you have hidden these things from the wise and the learned you have revealed them to the children." (Luke 10,21). We don´t oppose such revelations neither against the Revelation, nor against the Tradition, but we accept what the Holy Church accepts under the Holy Spirit discernment, some of them being exalted to the honours of the Sacred Liturgy. We don´t suppose to have the right to pose limits to the goodness and mercy of the Lord who inspires, speaks and operates in the heart of His believers, whenever and when He decides to do so.

     15º. Finally, our Fraternity intends to take ahead across the coming ages this blowing of the Holy Spirit that he stirred into flame of love to renew the face of the earth. Our Fraternity wishes this flame to be perpetuated in the whole world as a magnificent flaming light of an age that will quit being unfaithful and will return to the Lord as the converted and purified Bride of the Lamb (Rev.21,9).

     The very first requisite to enter or belong to the Fraternity, in some of its branches, is to be opened to such a spirituality, through the effective and devoted adherence to its fundamental principles. Such a requirement is based on the principle that the most important in a Community is that all its members are united in the same spirit that is inherent and unique therein.
