Sure! No problem!
…The Roman Catholic Church teaches many doctrines that are in disagreement with what the Bible declares.
The Church teaches that Jesus left us a Church, not a book. (Interestingly enough, in that book, you can see that this is true, and that Jesus promised His protection and aid would be given to the church He founded, and not the book they’d later write. ;))
These include apostolic succession
Apostolic succession is in the Bible. Look at Acts 1:15-26; they found a successor to the Apostle Judas.
, worship of saints or Mary
The Church doesn’t ‘worship’ anyone but God. We honor saints (including Mary), and that’s Scriptural, too. Paul constantly talks about the good things that the saints in the Church are doing!
, prayer to saints or Mary
Again, Scriptural. Look at Mark 12:27 – “you are greatly misled; God is the God of the living, not the dead”. We pray to the saints and Mary only inasmuch as we’re asking them to pray for us (which is, again, Scriptural), knowing that they’re alive in the spirit and we know that they pray for us (see Revelation 8).
, the pope / papacy
Matthew 16 – Jesus tells Peter that he will have “the keys to the kingdom” in the Church that He will found. Then in John 21, he confirms Peter’s ministry to “tend [Jesus’] sheep.”
Do we see him being called ‘pope’ in the Scriptures? No. Then again, did you call your mom “Mom” when you were newborn? Did that make her any less your mom, until you were able to call her ‘Mom’?
, infant baptism
In Acts, we see that whole households were being baptized. Not just the adults, mind you – whole households.
Transubstantiation is only the philosophical/metaphysical explanation ‘how’ the Eucharist takes place.
, plenary indulgences and purgatory…
An indulgence isn’t ‘forgiveness for sins’, it’s the remission of punishment due to (already forgiven) sin. We see it in 2 Maccabees – they prayed that their deceased friends should attain to heaven.
, the sacramental system,
Again, it’s Scriptural: “unless you eat my flesh and drink my blood, you have no life within you” – “do this in memory of me”. “Whose sins you forgive, are forgiven them in heaven.” “Baptize all nations in the name of the Father, and of the Son, and of the Holy Spirit.” All of these are Jesus’ own words in the Gospels.
…the Catholic Church also leads many people away from a genuine faith relationship with Christ…
It does? Where’s the evidence?
… The Roman Catholic Church is not the church that Jesus Christ established…"
Almost true. The Catholic Church (along with the Orthodox Church) is the church that Jesus Christ established. The various Reformation denominations (and the non-denominational communities) are the ones that were founded by men (and bear their names!) – 1500 years after Jesus founded His Church…
