It's good that you admire the Apostle Paul. Your admiration is a form of adoration. Catholics call on the Apostles, saints, and angels in heaven to pray God for us. I'm no specially brave soldier who can march through life, alone, without spiritual pathfinders. Being a sinner, on occasion, I find it necessary to muster all the help heaven can assemble. “Call now, if there be any that will answer thee, and turn to some of the saints.” (Job 5:1)
I suspect that part of the difference in our faiths is that Catholics, like many others, believe in a living faith. That is we celebrate life, both natural and spiritual. When death comes it doesn't separate us from those in the Kingdom of Heaven. Catholics believe in a community of saints that binds the faithful on earth with those souls in purgatory and those in heaven. Perhaps you don't hold to the same tenants but you may recall the Apostles Creed:
“ I believe in God the Father Almighty Creator of Heaven and earth And in Jesus Christ, His only Son, our Lord; (3) Who was conceived by the Holy Ghost, born of the Virgin Mary, Suffered under Pontius Pilate, was crucified, dead, and buried; He descended into hell; the third day He rose again from the dead ; He ascended into Heaven, sitteth at the right hand of God the Father Almighty; From thence He shall come to judge the living and the dead.
I believe in the Holy Ghost, 9) The Holy Catholic Church, the communion of saints The forgiveness of sins, 11) The resurrection of the body, an life everlasting." (Emphases is mine)
We believe that those faithful here on earth (the Church Militant) are in communion with our prayers with those in purgatory, the Church Suffering, and in communion with our prayers with those in Heaven, the Church Triumphant. This is a communion of the body of One Church transcending death through a spiritual unity in Christ. Thus, we hold that the saints can intercede with their prayers, and we hold the necessity of indulgencies, and the veneration of the saints. “… you are come to mount Sion and to the city of the living God, the heavenly Jerusalem, and to the company of many thousands of angels, And to the church of the firstborn who are written in the heavens, and to God the judge of all, and to the spirits of the just made perfect, And to Jesus the mediator of the new testament, and to the sprinkling of blood which speaketh better than that of Abel.” (Heb 12:12)
St. Thomas answers the issue of whether to pray to the saints.
Article 2. Whether we ought to call upon the saints to pray for us?:
... Further, the saints who are in heaven are more acceptable to God than those who are on the way. Now we should make the saints, who are on the way, our intercessors with God, after the example of the Apostle, who said (Romans 15:30): "I beseech you . . . brethren, through our Lord Jesus Christ, and by the charity of the Holy Ghost, that you help me in your prayers for me to God." Much more, therefore, should we ask the saints who are in heaven to help us by their prayers to God.( St. Thomas Aquinas, The Summa Theologica, III, supp, 72)
Article 3. Whether the prayers which the saints pour forth to God for us are always granted? :
It is written (2 Maccabees 15:14): "This is he that prayeth much for the people, and for all the holy city, Jeremias the prophet of God": and that his prayer was granted is clear from what follows (2 Maccabees 15:15): "Jeremias stretched forth his right hand, and gave to Judas a sword of gold, saying: Take this holy sword, a gift from God," etc.
Further, Jerome says (Ep. contra Vigilant.): "Thou sayest in thy pamphlets, that while we live, we can pray for one another, but that when we are dead no one's prayer for another will be heard": and afterwards he refutes this in the following words: "If the apostles and martyrs while yet in the body can pray for others, while they are still solicitous for themselves, how much more can they do so when the crown, the victory, the triumph is already theirs!"
Further, this is confirmed by the custom of the Church, which often asks to be assisted by the prayers of the saints. (St. Thomas Aquinas, The Summa Theologica, III, supp, 72)
