Answering Islam·Jul 14, 2026 Early Church, John 16:13, Perichoresis & the Filioque
The Catholic Church teaches that Christians have always believed and affirmed the Filioque, e.g., the Father spiritually breathes/spirates the Holy Spirit through the Son timelessly, eternally. This in turn makes the Holy Spirit the Spirit of both the Father and the Son, which is precisely what the inspired Scriptures proclaim (cf. Acts 16:6-7; Rom. 8:9-17; Gal. 4:4-6; Phil. 1:19; 1 Pet. 1:10-12).
