let me put in some of my own answers
#1: Why do you pray to Mary rather than God?
we don’t pray to Mary RATHER than to God
we pray to Mary to pray for us to God, on top of praying to God as well
#2: Why do you confess to a priest rather than to God?
we confess to a preist because sin not only damages our relationship to God, it also damages our relationship to the Church of Jesus Christ. if we pray to God and sincerely in our hearts we are repentant, God may forgive our sins and we are reconcilled with God. but we must also reconcile with the Church and this is done through confession to a priest because Jesus passed on this authority to the apostles and their successors. here are the three paragraphs from the CCC
Reconciliation with the Church
1443 During his public life Jesus not only forgave sins, but also made plain the effect of this forgiveness: he reintegrated forgiven sinners into the community of the People of God from which sin had alienated or even excluded them. A remarkable sign of this is the fact that Jesus receives sinners at his table, a gesture that expresses in an astonishing way both God’s forgiveness and the return to the bosom of the People of God.44
1444 In imparting to his apostles his own power to forgive sins the Lord also gives them the authority to reconcile sinners with the Church. This ecclesial dimension of their task is expressed most notably in Christ’s solemn words to Simon Peter: "I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."45 "The office of binding and loosing which was given to Peter was also assigned to the college of the apostles united to its head."46
1445 The words bind and loose mean: whomever you exclude from your communion, will be excluded from communion with God; whomever you receive anew into your communion, God will welcome back into his. Reconciliation with the Church is inseparable from reconciliation with God.
#3: What’s the deal with having a pope and saints?
Peter is the leader of the Apostles and to whom Jesus entrusted the keys of Heaven and upon whom He built His Church. the Pope is merely the successor of Peter
Saints are everyone in heaven. The Catholic Church just recognize a few of them so that the faithful may have human example on how to be more Christ-like. A lot of people can easily say that its hard to follow what Jesus did and its easy for Him because He is God. But if we’re presented with a human being like Mother Theresa (not yet recognized as a saint but in my mind i know she already is) who lived among us in modern times and yet did the work of Jesus, it should inspire us to do the same. hey, she’s human like you and me and she was able to do it, so why can’t we?
Plus, knowing these people already in the presence of God, we can ask them to pray for us as their prayers are more effective being already in the presence of God in Heaven
#4: Do you preach in your churches or is it all ritual?
the priest would deliver a Homily after the Gospel has been read
there are also many other activities in the Church which would provide scriptural learning. I belong to a small parish but every night of the week there’s something going on, like Bible Studies, learning about Pope John Paul II’s Theology of the Body, Catechism classes, RCIA which is opened not only for those wishing to join the Catholic Church but also for Catholics who would want to understand their faith better
#5: Why do you annoint with oil?
from the CCC (chapter on Confirmation)
1289 Very early, the better to signify the gift of the Holy Spirit, an anointing with perfumed oil (chrism) was added to the laying on of hands. This anointing highlights the name “Christian,” which means “anointed” and derives from that of Christ himself whom God "anointed with the Holy Spirit."100 This rite of anointing has continued ever since, in both East and West. For this reason the Eastern Churches call this sacrament Chrismation, anointing with chrism, or myron which means “chrism.” In the West, the term Confirmation suggests that this sacrament both confirms and strengthens baptismal grace.
1293 In treating the rite of Confirmation, it is fitting to consider the sign of anointing and what it signifies and imprints: a spiritual seal.
Anointing, in Biblical and other ancient symbolism, is rich in meaning: oil is a sign of abundance and joy;103 it cleanses (anointing before and after a bath) and limbers (the anointing of athletes and wrestlers); oil is a sign of healing, since it is soothing to bruises and wounds;104 and it makes radiant with beauty, health, and strength.
1294 Anointing with oil has all these meanings in the sacramental life. The pre-baptismal anointing with the oil of catechumens signifies cleansing and strengthening; the anointing of the sick expresses healing and comfort. The post-baptismal anointing with sacred chrism in Confirmation and ordination is the sign of consecration. By Confirmation Christians, that is, those who are anointed, share more completely in the mission of Jesus Christ and the fullness of the Holy Spirit with which he is filled, so that their lives may give off "the aroma of Christ."105
#6: Do you always agree with what the pope declares or says?
there are those who object. but in our hearts we believe that the Pope merely carries out what the Holy Spirit directs him to do or say. and yet the Pope is also human and subject to temptation and mistakes. that is why all Catholics should pray for the Pope every single minute, that may he remain faithful to the teachings if Jesus and lead us all to Him.
