CCC 752

In Christian usage, the word "church" designates the liturgical assembly,¹⁴¹ Cf.1 Cor 11:18; 14:19, 28, 34, 35. but also the local community¹⁴² Cf. 1 Cor 1:2; 16:1. or the whole universal community of believers.¹⁴³ Cf. 1 Cor 15:9; Gal 1:13; Phil 3:6. These three meanings are inseparable. "The Church" is the People that God gathers in the whole world. She exists in local communities and is made real as a liturgical, above all a Eucharistic, assembly. She draws her life from the word and the Body of Christ and so herself becomes Christ's Body.
