Catholics always say that Peter was the first pope, the rock, the key holder of the Catholic Church. But what about Paul? In a way I think Paul really made Christianity what it is today. He was the one who declared all Gentiles were part of the kingdom of Israel, descendants of Abraham, just as the Jews were. He was the one who denounced the Jewish laws (such as circumcism and dietary restrictions), and told all people that they could be saved only by grace and the crucifixion of Jesus.
What do you think, both Catholics and non-Catholics? Who was most important, Peter or Paul?
I think the question is not right and should not be asked by Christians. Unless it is for the sake of childish comparison and for fun.
All saints are members of the one body in Christ and each has unique role to play. As to who is more important, the question does not arise as all are important in the eyes of the Lord.
I think Paul says it very well here:
1 Cor 12
2 You remember that, when you were pagans, you were irresistibly drawn to inarticulate heathen gods.
3 Because of that, I want to make it quite clear to you that no one who says ‘A curse on Jesus’ can be speaking in the Spirit of God, and nobody is able to say, ‘Jesus is Lord’ except in the Holy Spirit.
4 There are many different gifts, but it is always the same Spirit;
5 there are many different ways of serving, but it is always the same Lord.
6 There are many different forms of activity, but in everybody it is the same God who is at work in them all.
14 And indeed the body consists not of one member but of many.
15 If the foot were to say, ‘I am not a hand and so I do not belong to the body,’ it does not belong to the body any the less for that.
16 Or if the ear were to say, ‘I am not an eye, and so I do not belong to the body,’ that would not stop its belonging to the body.
17 If the whole body were just an eye, how would there be any hearing? If the whole body were hearing, how would there be any smelling?
18 As it is, God has put all the separate parts into the body as he chose.
Ephesan 4
4 There is one Body, one Spirit, just as one hope is the goal of your calling by God.
5 There is one Lord, one faith, one baptism,
6 and one God and Father of all, over all, through all and within all.
7 On each one of us God’s favour has been bestowed in whatever way Christ allotted it.
8 That is why it says: He went up to the heights, took captives, he gave gifts to humanity.
9 When it says, ‘he went up’, it must mean that he had gone down to the deepest levels of the earth.
10 The one who went down is none other than the one who went up above all the heavens to fill all things.
**11 And to some, his ‘gift’ was that they should be apostles; to some prophets; to some, evangelists; to some, pastors and teachers;
12 to knit God’s holy people together for the work of service to build up the Body of Christ, **
13 until we all reach unity in faith and knowledge of the Son of God and form the perfect Man, fully mature with the fullness of Christ himself.
