The Church of Christ is infallible in doctrine and morals promulgated as the faith, even though members of the Church of Christ fail to be clothed in Christ.
If a doctrine is infallible then evil cannot touch it, which is exactly my point.
The reason why Satan cannot infiltrate Jesus such as in the desert is because his doctrine is solid. It is not just doctrine, because doctrine is in the the realms of man. As such it is a guiding force. But rather, unlike the Pharisee, it is doctrine adhered to in action as well as words. As such we can say for certain that Jesus’s doctrine is infallible. However, Catholic doctrine goes outside of Jesus’s doctrine, adding more, such as doctrines imposed by Paul and early other bishops who’s actions, say like, where Paul approves of stoning Stephen, are in deep contrast to Jesus’s teachings, and have been utilized in order to create some of the most evil acts known to modern humanity.
As such doctrine is liable to misinterpretation. This misinterpretation or maybe a better word is misrepresentation, is what makes doctrine in itself fallible. Exactly as you rightly point out about the Pharisee, saying one thing and doing another. And it could be surmised that Catholics and Pharasee can be interchangeable in some respects on this point.
It is here that Pope John Paul 2 did what no other pope before him having the ability to do in the Jubalee of forgivness:
Merciful Father,
on the night before his Passion
your Son prayed for the unity of those who believe in him:
in disobedience to his will, however,
believers have opposed one another, becoming divided,
and have mutually condemned one another and fought against one another.
We urgently implore your forgiveness
and we beseech the gift of a repentant heart,
so that all Christians, reconciled with you and with one another
will be able, in one body and in one spirit,
to experience anew the joy of full communion.
We ask this through Christ our Lord.
That is admitting to the sins of the church (as a membership) over time and asking for forgiveness. Now when we forgive someone we do so in recognition of their wrongs and that those wrongs will not be repeated.
Let us pray that contemplating Jesus,
our Lord and our Peace,
Christians will be able to repent of the words and attitudes
caused by pride, by hatred,
by the desire to dominate others,
by enmity towards members of other religions
and towards the weakest groups in society,
such as immigrants and itinerantes
God, our Father,
you always bear the cry of the poor.
How many times have Christians themselves not recognized you
in the hungry, the thirsty and the naked,
in the persecuted, the imprisoned,
and in those incapable of defending themselves,
especially in the first stages of life.
For all those who bave committed acts of injustice
by trusting in wealth and power
and showing contempt for the “little ones”
who are so dear to you, we ask your fogiveness:
have mercy on us and accept our repentance.
We ask this through Christ our Lord.
These are the reasons why the voice of god who resides in all our hearts, Catholic or not, is higher than any specific doctrine (children for example know not doctrine- yet are held by Jesus as the highest) because doctrine itself is open to interpretation and can be a tool of harm by a collective or membership of a Church.
Further many great evil deeds could have been alleviated if in fact Catholics had followed this simple doctrine rather than the words of Church leader. For if a evil person or a pedophile was in your midst, god would let your heart know.
