I didnt know that
I wonder if all Irish know that story...?
My mother used to tell me about the Trinity as she oiled her old Singer sewing machine (1939 model)
The oil was made by Singer and called 3-in-1...
She called it her Holy 3-in-1 Oil...
My mother loved God and was a Christian and she wasnt being sacrilegious..
She just wanted to teach me her faith in God...
And for some reason I understood the Trinity as a child...
157. The solemnity of the Most Holy Trinity is celebrated on the Sunday after Pentecost. With the growth of devotion to the mystery of God in His Unity and Trinity, John XXII extended the feast of the Holy Trinity to the entire Latin Church in 1334. During the middle ages, especially during the carolingian period, devotion to the Blessed Trinity was a highly important feature of private devotion and inspired several liturgical expressions. These events were influential in the development of certain pious exercises.
In the present context, it would not appear appropriate to mention specific pious exercises connected with popular devotion to the Blessed Trinity, "the central mystery of the faith and of the Christian life"165. It sufficies to recall that every genuine form of popular piety must necessarily refer to God, "the all-powerful Father, His only begotten Son and the Holy Spirit"166. Such is the mystery of God, as revealed in Christ and through him. Such have been his manifestations in salvation history. The history of salvation "is the history of the revelation of the one true God: Father, Son and Holy Spirit, who reconciles and unites to Himself those who have been freed from sin" 167.
Numerous pious exercises have a Trinitarian character or dimension. Most of them begin with the sign of the cross "in the name of the Father, and of the Son, and of the Holy Spirit", the same formula with which the disciples of Jesus are baptized (cf. Mt 28, 19), thereby beginning a life of intimacy with the God, as sons of the Father, brothers of Jesus, and temples of the Holy Spirit. Other pious exercises use formulas similar to those found in the Liturgy of the Hours and begin by giving "Glory to the Father, Son, and Holy Spirit". Some pious exercises end with a blessing given in the name of the three divine Persons. Many of the prayers used in these pious exercises follow the typical liturgical form and are addressed to the "Father, through Christ, in the Holy Spirit", and conserve doxological formulas taken from the Liturgy.
158. Worship, as has been said in the first part of this Directory, is the dialogue of God with man through Christ in the Holy Spirit168. A Trinitarian orientation is therefore an essential element in popular piety. It should be clear to the faithful that all pious exercises in honour of the Blessed Virgin May, and of the Angels and Saints have the Father as their final end, from Whom all thing come and to Whom all things return; the incarnate, dead and resurrected Son is the only mediator (1Tim 2,5) apart from whom access to the Father is impossible (cf. John 14,6); the Holy Spirit is the only source of grace and sanctification. It is important to avoid any concept of "divinity" which is abstract from the three Divine Persons.
159. Together with the little doxology (Glory be to the Father, and to the Son, and to the Holy Spirit....) and the great doxology (Glory be to God in the highest), pious exercises addressed directly to the Most Blessed Trinity often include formulas such as the biblical Trisagion (Holy, Holy, Holy) and also its liturgical form (Holy God, Holy Strong One, Holy Immortal One, have mercy on us), especially in the Eastern Churches, in some Western countries as well as among numerous religious orders and congregations.
The liturgical Trisagion is inspired by liturgical hymns and its biblical counterpart. Here mention could be made of the Sanctus used in the celebration of the Mass, the Te Deum, the improperia of Good Friday's veneration of the Cross, all of which are derived from Isaiah 6, 3 and Apocalypses 4, 8. The Trisagion is a pious exercise in which the faithful, united with the Angels, continually glorify God, the Holy, Powerful and Immortal One, while using expressions of praise drawn from Scripture and the Liturgy.
