Christians are the new People of God, chosen by Him.

Every disciple of Christ is obligated to spread the faith.

It is not unreasonable to assert that the New Testament implicitly teaches the immorality of pharmaceutical abortion, claims that the Bible does not touch on the topic ignores the common jewish and pagan literary background of the time where abortion through pharmakeia was common.

Levels of Magisterial Teaching Authority (Dissertation "The Authoritative Weight of Non-Definitive Magisterial Teaching" by Dr. Lawrence King)

Do not incite hatred or animosity against bishops or the Apostolic See.

"Whatever opinion one may profess on the infallibility of the pope, it is just as disrespectful to proclaim publicly that he can be wrong, as to say to children: your parents may be lying to you." (Paul Nau, "The Ordinary Magisterium of the Catholic Church)

St. Polycarp offers a vision of presbyters both as being called to mercy, calling sinners back to the flock of Christ, while also encouraging meticulous following of Christ's teachings. He says that we must shun "false brothers" and "those who assume the Lord's name hypocritically". This is the Christian vision: repentance leads us to accept God's mercy followed by life in Christ, departing from Jesus while trying to retain His name avails nothing.

"The attachment of the heterodox to Vatican II is opportunism, not assent to the magisterium. This is why you won't persuade them by quoting its doctrinal statements, even where these rise to definitions. A conversion of the heart is needed."

Catholics believe that baptism fully remits our sins. Not only does it wash away original sin, filling us with God's sanctifying grace, but it also washes away all personal sin and the temporal punishment due for it. All sins prior to baptism are completely cleansed, if you died immediately after baptism your soul would immediately enter heaven (no purgation needed).

(The Catholic Encyclopedia on Baptism)

"We are always tempted to start from ourselves rather than from God, to put our own agendas before the Gospel, to let ourselves be caught up in the winds of worldliness in order to chase after the fashions of the moment or to turn our back on the time that Providence has granted us, in order to retrace our steps. Yet let us be careful: both the “progressivism” that lines up behind the world and the “traditionalism” – or “looking backwards” – that longs for a bygone world are not evidence of love, but of infidelity. They are forms of a Pelagian selfishness that puts our own tastes and plans above the love that pleases God, the simple, humble and faithful love that Jesus asked of Peter."

This is precisely why the nation is so important. The nation should draw us out from ourselves, keeping us from subjectivism by holding out a reality distinct from the individual. If our society, nations, get infected with subjective individualism they will undermine each individual within the society and thus undermine the society as a whole (On Conscience: Two Essays, Ignatius Press)
