"The Catholic church is not the problem if it means the universal church (creed). It is a problem if it means the Roman Catholic Church."
This is a distinction without a difference. It is only a problem if one chooses to believe it is not one in the same.
"Some unbiblical concerns would include purgatory"
This, like the Trinity, can be deduced although it is not mentioned by name. If we are not in a state of grace, nothing unclean will enter heaven (Revelation 21:27).
1 John 5:16-17 (Revised Standard Version)
16 If any one sees his brother committing what is not a mortal sin, he will ask, and God will give him life for those whose sin is not mortal. There is sin which is mortal; I do not say that one is to pray for that. 17 All wrongdoing is sin, but there is sin which is not mortal.
When we die in sin, but the sin is not deadly, where do we go? What happens to us? We know we do not gain immediate entry into heaven, since nothing unclean can enter there (see Rev. 21:27). And it certainly can't be hell, since John tells us the sin is not deadly. We must therefore undergo some sort of cleansing or "purgation".
Matthew 12:32 (RSV)
32 "And whoever says a word against the Son of man will be forgiven; but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come."
Here Jesus clearly implies that expiation can occur after death. Apparently some sins are forgiven in the "age to come".
Rosary/Marian issues/Intercession of Saints,
I included all three of these since they usually stem from the same misunderstanding of the Church's teachings about Mary and the saints. And we pray with the saints, not to them.
The Rosary is a meditation of the Gospels:
"Hail, full of grace, the Lord is with thee" (Luke 1:28)
"Blessed art thou amongst women and blessed is the fruit of thy womb" (Luke 1:42)
"Holy Mary, Mother of God, pray for us sinners, now and at the hour of our death. Amen." This is asking Mary, the mother of Christ's humanity, to pray for us. This is no different than myself asking you to pray for me. She and the saints are just as alive as you or I are.
Hebrews 12:1 (RSV)
1 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with perseverance the race that is set before us
Paul asks for those to pray for one another in 1 Timothy 2:1-3 (RSV)
"First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men, 2 for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way. 3 This is good, and it is acceptable in the sight of God our Savior"
Acts 12:5 (RSV)
5 So Peter was kept in prison; but earnest prayer for him was made to God by the church.
This is a clear example of intercessory prayer. It is one of many in Sacred Scripture. Abraham interceeded for Sodom in Genesis 18, and Moses constantly interceeded for the Hebrews.
"apostolic succession"
St Paul and St Barnabas ordain others in Acts 14:23. No one ordains himself, nor does anyone presume to act as presbyter without first being ordained.
The Church's authority is passed from generation to generation in Acts 6:6 (RSV)
6 These they set before the apostles, and they prayed and laid their hands upon them.
and Acts 1:20-26 (RSV)
20 For it is written in the book of Psalms, 'Let his habitation become desolate, and let there be no one to live in it'; and 'His office let another take.' 21 So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us, 22 beginning from the baptism of John until the day when he was taken up from us--one of these men must become with us a witness to his resurrection." 23 And they put forward two, Joseph called Barsab'bas, who was surnamed Justus, and Matthi'as. 24 And they prayed and said, "Lord, who knowest the hearts of all men, show which one of these two thou hast chosen 25 to take the place in this ministry and apostleship from which Judas turned aside, to go to his own place." 26 And they cast lots for them, and the lot fell on Matthi'as; and he was enrolled with the eleven apostles.
1 Timothy 3:1 (RSV)
1 The saying is sure: If any one aspires to the office of bishop, he desires a noble task.
"Office" denotes an ongoing institution that is renewed from one generation to the next. Otherwise, why bother replacing Judas?
Scripture+Tradition
2 Thessalonians 2:15 (RSV)
15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter
2 Thessalonians 3:6 (RSV)
6 Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from any brother who is living in idleness and not in accord with the tradition that you received from us.
1 Corinthians 11:2 (RSV)
2 I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you.
So you can see, tradition is not unbiblical.
Faith+Works
James 2:14-26
14 What does it profit, my brethren, if a man says he has faith but has not works? Can his faith save him? 15 If a brother or sister is ill-clad and in lack of daily food, 16 and one of you says to them, "Go in peace, be warmed and filled," without giving them the things needed for the body, what does it profit? 17 So faith by itself, if it has no works, is dead. 18 But some one will say, "You have faith and I have works." Show me your faith apart from your works, and I by my works will show you my faith. 19 You believe that God is one; you do well. Even the demons believe--and shudder. 20 Do you want to be shown, you shallow man, that faith apart from works is barren? 21 Was not Abraham our father justified by works, when he offered his son Isaac upon the altar? 22 You see that faith was active along with his works, and faith was completed by works, 23 and the scripture was fulfilled which says, "Abraham believed God, and it was reckoned to him as righteousness"; and he was called the friend of God. 24 You see that a man is justified by works and not by faith alone. 25 And in the same way was not also Rahab the harlot justified by works when she received the messengers and sent them out another way? 26 For as the body apart from the spirit is dead, so faith apart from works is dead.
Matthew 7:21-23
21 "Not every one who says to me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of my Father who is in heaven. 22 On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' 23 And then will I declare to them, 'I never knew you; depart from me, you evildoers.'
Jesus is saying that judgement will be based on how we live out our faith (he who DOES THE WILL of His Father), not on "faith alone".
John 5:29
29 and come forth, those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of judgment.
Deeds will indeed be judged.
infant baptism=born again
Luke 18:15-17
15 Now they were bringing even infants to him that he might touch them; and when the disciples saw it, they rebuked them. 16 But Jesus called them to him, saying, "Let the children come to me, and do not hinder them; for to such belongs the kingdom of God. 17 Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it."
Acts 16:33
33 "And he took them the same hour of the night, and washed their wounds, and he was baptized at once, with all his family"
Entire households, with no exceptions, were baptized.
Luke 1:15
15 for he will be great before the Lord, and he shall drink no wine nor strong drink, and he will be filled with the Holy Spirit, even from his mother's womb.
If no one can receive the Holy Spirit without repentance, then we must conclude that infants are able to repent even in utero, since in this passage we see that St John the Baptist was filled with the Holy Spirit even before his birth. Which means there is no reason to deny infants the Sacrament of Baptism.
I'll address the Mass and Indulgences in the next post.....
