- true liturgy, i.e., the Mass celebrated in continuity with Holy Tradition. For the Catholic, the Holy Eucharist is "the source and summit of the Christian life". A Catholic is a Christian who is in communion with Christ and His Church. Communities that will thrive are those 1) in which the word of God is faithfully proclaimed and 2) in which is hosted the good, the true and the beautiful celebration of the Mass oriented to God. Conversely, communities marred by self-centred worship and loose play with the Apostolic Tradition (Scripture and Tradition) will wither and become little more than social clubs wearing a religious veneer.
- true teaching. A diet of orthodox Catholic theology forms disciples worthy of the name Christian.
- vigorous and true spiritual discipline(s) (e.g., the Spiritual and Corporal Works of Mercy, the Holy Rosary, Lectio Divina and the Divine Office) oriented to Jesus Christ and the Most Holy Trinity. People and priests maintain ongoing formation in prayer. Disciples keep the Lord's commandments because they love the Lord (cf. John 14:21).
- true joy and hope. True disciples of Christ are a people of hope. They see and meet Christ in their neighbour, enemy or friend. True disciples are a people of Truth, Goodness and Beauty in the Lord. True disciples are children of the Father in Christ Jesus by the Holy Spirit.
- unfailing self-sacrificing love. The Church that survives and thrives is moved and shaped in and through intimate communion with the Most Holy Trinity. True love follows in the footsteps of the suffering Servant, Jesus Christ, Who shows us the way of love and the way to everlasting life.
