The pope and all priests, reverends or rabbis are deserving of anything he requests and his parish or congregation is willing to bestow on him. After all, it’s a gathering of believers. If they believe something strong enough, sure, go for it.
Belief? Is not enough, Demons believe and tremble in fear. "You believe there is one God. You do well. Even the demons believe-and tremble." -- James 2:19
Indeed the term "Believer" is used in scripture to denote/identify Christians who have entered the kingdom/church of Jesus Christ, "And believers were increasingly added onto The Lord, multitudes of both men and women." -- Acts 15:4 also stated in (Acts 10:45, 16:1, 2 Cor. 6:15, 1 Thess. 1:7, 2:10, 1 Tim. 4:10, 5:16, 6:2, 1 Peter 1:21).
But.......every person that believes is not necessarily "saved" or added to the kingdom. There is more required to enter the kingdom than belief alone. "Repent and be baptized in the name of Jesus Christ and you will receive the GIFT of the HOLY SPIRIT" -- Acts 2:38.
Another example: Cornelius was a man of FAITH/BELIEF in that he believed in God. (Acts 10:2), but......God instructed him to send for the Apostle Peter and Peter would tell him what must be done to enter the kingdom of Christ (Acts 11:14) He, Cornelius did not became a true believer until he acted or presented the works of one that believes in a demonstration of his faith.
What did Peter tell Cornelius? All those in the household that heard Peter preach the gospel truth........believed, and were Baptized in water (which represents a physical death/burial and resurrection into a new man/woman. Baptism is a required work of faith. (Acts 10:47-48). Even though the Holy Spirit fell upon the house of Cornelius, they did not enter the kingdom/church until they were baptized. The Holy Spirit fell upon this gentile household like it did upon the Jews in Acts 2, none of the Jews present when the Spirit fell upon the 12 were saved......allowed to enter the kingdom until they repented and were baptized in water in the name of Jesus Christ.
The Spirit fell upon the household of Cornelius also as it did upon the Jews in Acts 2............to prove that Christianity was acceptable to gentiles as well as Jews. There are only 2 records of anyone being baptized in the Holy Spirit in the entire New Testament. Once on the day of Pentecost following the ascension of Christ into heaven and at the house of Cornelius (a gentile family) -- Acts 10
"Yea, man may say, Thou hast faith, and I have works; show me thou faith without works and I will show you my faith by my works." -- James 2:17
Faith without WORKS is DEAD. (James 2:17). Not everyone who claims they believe will find salvation. "Not everyone who says to Me, Lord! Lord! will enter the kingdom of heaven (the church/kingdom of Christ, kingdom of God........all are used synonymously in the N.T. record).......depart from Me, I never knew you........" -- Matt. 7:21-23
Jesus declared that man made traditions were not acceptable doctrine in the eyes of God.......traditions make the Scriptures none effective. Jesus informed those of the 1st century of this truth, TRADITIONS, "make the Word of God (scripture) of no effect .........through traditions that ye have delivered; and many such things ye do....." -- Mark 7:13, Matt. 15:6
If something was TRUE in the 1st century...........God looks down upon man made traditions taking the place of His Holy Scriptures......its just as true in the 21st century, Truth does not evolve.
