15 But speaking the truth in love, we must grow up in every way into him who is the head, into Christ, 16 from whom the whole body, joined and knitted together by every ligament with which it is equipped, as each part is working properly, promotes the body’s growth in building itself up in love.
Book of Confessions, 3.16
As we believe in one God, Father, Son, and Holy Ghost, so we firmly believe that from the beginning there has been, now is, and to the end of the world shall be, one Kirk, that is to say, one company and multitude of men chosen by God, who rightly worship and embrace him by true faith in Christ Jesus, who is the only Head of the Kirk, even as it is the body and spouse of Christ Jesus. This Kirk is catholic, that is, universal, because it contains the chosen of all ages, of all realms, nations, and tongues, be they of the Jews or be they of the Gentiles, who have communion and society with God the Father, and with his Son, Christ Jesus, through the sanctification of his Holy Spirit. It is therefore called the communion, not of profane persons, but of saints, who, as citizens of the heavenly Jerusalem, have the fruit of inestimable benefits, one God, one Lord Jesus, one faith, and one baptism. Out of this Kirk there is neither life nor eternal felicity. Therefore we utterly abhor the blasphemy of those who hold that men who live according to equity and justice shall be saved, no matter what religion they profess. For since there is neither life nor salvation without Christ Jesus; so shall none have part therein but those whom the Father has given unto his Son Christ Jesus, and those who in time come to him, avow his doctrine, and believe in him. (We include the children with the believing parents.) This Kirk is invisible, known only to God, who alone knows whom he has chosen, and includes both the chosen who are departed, the Kirk triumphant, those who yet live and fight against sin and Satan, and those who shall live hereafter.
