Heidelberg Catechism: 'Why must He be a true and sinless man?'


Second Part: God’s Grace (Cont.)

LORD’S DAY 6

16. Why must He be a true and sinless man?

Because the justice of God requires that the same human nature which has sinned should make satisfaction for sin;1 but no man, being himself a sinner, could satisfy for others.2

1 Rom 5:12, 15; 1 Cor 15:21; Heb 2:14-16; 2 Heb 7:26-27; 1 Pt 3:18

17. Why must He be at the same time true God?

That by the power of His divine nature1 He might bear in His human nature the burden of God’s wrath2 and so obtain for and restore to us righteousness and life.3

1 Isa 9:5; 2 Deut 4:24; Nah 1:6; Ps 130:3; 3 Isa 53:5, 11; Jn 3:16; 2 Cor 5:21

18. But who is that Mediator, who is at the same time true God and a true, sinless man?

Our Lord Jesus Christ,1 who is freely given unto us for complete redemption and righteousness.2

1 Mt 1:21-23; Lk 2:11; 1 Tim 2:5, 3:16; 2 1 Cor 1:30

19. From where do you know this?

From the Holy Gospel, which God Himself first revealed in Paradise;1 afterwards proclaimed by the holy Patriarchs2 and Prophets,3 and foreshadowed by the sacrifices and other ceremonies of the Law;4 and finally fulfilled by His well-beloved Son.5

1 Gen 3:15; 2 Gen 12:3, 22:18, 49:10; 3 Isa 53: Jer 23:5-6; Mic 7:18-20; Acts 10:43; Heb 1:1; 4 Lev 1:7; Jn 5:46; Heb 10:1-10; 5 Rom 10:4; Gal 4:4-5; Col 2:17
