Matthew 22:14 with a stroke explodes the notion of hyper-Calvinists that only convicted sinners, or the elect are called by the gospel. You cannot know who your audience are! Only in the sense that the call is the effectual call is this correct. But in the sense that the external call of the gospel*, preached by men, with the command to repent and believe is to go to all nations promiscuously, they are wrong. Christ clearly differentiates between the outward preached call* to the many, and the inward effectual call** from death to life that he accomplishes in the few. One asterisk* equates with the outward call and two** to the inward call.
This is corroborated in the Canons of Dort Heads III/IV Articles 8-10.
Article 8. As many as are called** by the gospel, are unfeignedly called**. For God hath most earnestly and truly shown in his Word, what is pleasing to him, namely, that those who are called** should come to him. He, moreover, seriously promises eternal life, and rest, to as many as shall come to him, and believe on him.
Article 9. It is not the fault of the gospel, nor of Christ, offered therein, nor of God, who calls men by the gospel*, and confers upon them various gifts, that those who are called* by the ministry of the word, refuse to come, and be converted: the fault lies in themselves; some of whom when called*, regardless of their danger, reject the word of life; others, though they receive it, suffer it not to make a lasting impression on their heart; therefore, their joy, arising only from a temporary faith, soon vanishes, and they fall away; while others choke the seed of the word by perplexing cares, and the pleasures of this world, and produce no fruit. – This our Savior teaches in the parable of the sower. Matthew 13.
Article 10. But that others who are called* by the gospel, obey the call, and are converted, is not to be ascribed to the proper exercise of free will, whereby one distinguishes himself above others, equally furnished with grace sufficient for faith and conversions, as the proud heresy of Pelagius maintains; but it must be wholly ascribed to God, who as he has chosen his own from eternity in Christ, so he confers upon them faith and repentance, rescues them from the power of darkness, and translates them into the kingdom of his own Son, that they may show forth the praises of him, who hath called** them out of darkness into his marvelous light; and may glory not in themselves, but in the Lord according to the testimony of the apostles in various places.
