87. The proclamation of the Good News by word and deed opens people's hearts to the desire for holiness, for being configured to Christ. In his First Letter to the Corinthians, Saint Paul addresses "those sanctified in Christ Jesus, called to be saints, together with all those who in every place call on the name of our Lord Jesus Christ" (1:2). Preaching the Gospel also aims to build up the Church of God, in the light of the coming of the Kingdom, which Christ will hand over to the Father at the end of time (cf. 1 Cor 15:24).

"Entrance into the Kingdom of God demands a change of mentality (metanoia) and behaviour and a life of witness in word and deed, a life nourished in the Church by the reception of the sacraments, particularly the Eucharist, the Sacrament of salvation".167

Inculturation, through which the faith penetrates the life of individuals and their primary communities, is also a path to holiness. Just as in the Incarnation Christ assumed human nature in everything but sin, analogously through inculturation the Christian message assimilates the values of the society to which it is proclaimed, rejecting whatever is marked by sin. To the extent that an ecclesial community can integrate the positive values of a specific culture, inculturation becomes an instrument by which the community opens itself to the riches of Christian holiness. An inculturation wisely carried out purifies and elevates the cultures of the various peoples.

From this point of view the liturgy is called to play an important role. As an effective way of proclaiming and living the mysteries of salvation, the liturgy can make a valid contribution towards the elevation and enrichment of specific manifestations of the culture of a people. It will therefore be the task of competent authority to see to the inculturation of those liturgical elements which, following artistically worthy models, can be changed in the light of current norms.168
