Rank
First-class feast
Trinity Sunday falls in the Season of Time after Pentecost, the liturgical weeks that follow Easter and Pentecost as the Church lives out the implications of Christ’s resurrection and the coming of the Holy Spirit. This day celebrates the Most Holy Trinity — Father, Son, and Holy Spirit — the one God in three persons. The rank “Double of the I Class” indicates a very solemn feast in the older divino_afflatu calendar: liturgically it outranks ordinary weekday observances and calls for fuller celebration, with its propers, prayers, and often special music. No octave or vigil is attached here beyond the single feast day.

Commandment 8
The Ten Commandments
Thou shalt not bear false witness.
The Eighth Commandment requires truthfulness and respect for another person’s good name. It forbids lies, false testimony, rash judgment, slander, detraction, and the needless disclosure of faults, because justice and charity both govern speech.

Catechism
Catechism of the Catholic Church
Confirmation perfects the grace received at Baptism, giving the Holy Spirit to root us more deeply in our divine filiation, strengthen our union with Christ and the Church, and help us witness to the Christian faith through both words and deeds. It seals the Christian with an indelible spiritual mark and can therefore be received only once. In the Eastern tradition, Confirmation is given immediately after Baptism and followed by the Eucharist, highlighting the unity of Christian initiation. When Confirmation is celebrated separately from Baptism, the renewal of baptismal promises expresses its close connection with Baptism. Candidates who have reached the age of reason are called to profess the faith, be in the state of grace, intend to receive the sacrament, and prepare to live as disciples and witnesses of Christ in the Church and in the world.
Through the sacraments of Christian initiation, we receive the new life of Christ. Yet we still live with human frailty, suffering, illness, death, and the inclination to sin, so this new life can be weakened or even lost by sin. In his mercy, the Lord continues his work of healing and salvation in the Church through the sacraments of Penance and Anointing of the Sick. In Penance, we confess our sins and receive God’s pardon and peace, being reconciled with God and with the Church. As we pray together, let us remember our call to conversion, forgive one another, and rely on Christ’s grace as we strive for holiness and eternal life.
¶ 1318
In the East this sacrament is administered immediately after Baptism and is followed by participation in the Eucharist; this tradition highlights the unity of the three sacraments of Christian initiation. In the Latin Church this sacrament is administered when the age of reason has been reached, and its celebration is ordinarily reserved to the bishop, thus signifying that this sacrament strengthens the ecclesial bond.
