The “door of faith” (Acts 14:27) is always open for us, ushering us into the life of communion with God and offering entry into his Church. It is possible to cross that threshold when the word of God is proclaimed and the heart allows itself to be shaped by transforming grace. To enter through that door is to set out on a journey that lasts a lifetime. It begins with baptism (cf. Rom 6:4), through which we can address God as Father, and it ends with the passage through death to eternal life, fruit of the resurrection of the Lord Jesus, whose will it was, by the gift of the Holy Spirit, to draw those who believe in him into his own glory (cf. Jn 17:22). To profess faith in the Trinity – Father, Son and Holy Spirit – is to believe in one God who is Love (cf. 1 Jn 4:8): the Father, who in the fullness of time sent his Son for our salvation; Jesus Christ, who in the mystery of his death and resurrection redeemed the world; the Holy Spirit, who leads the Church across the centuries as we await the Lord’s glorious return.
