A Muslim, a Jew, a Christian, and an atheist walk into a coffee shop...

[Catholic_Lady]

It would seem that one can be inspired to develop a profound and sincere care for their neighbor... without s/he ultimately possessing an ulterior motive, namely, seeking to win that person's soul over to the kingdom... that is, unless we actually accept Jesus in the other half of his moods, not the picturesque Christ in Sunday school who sits children on his lap while gentle little lambs gather around, but those precious moments spent of his short life wherein he wandered about, raving about the imminent Day of Judgment.

Do they just... pretend that part was lost in time as it should have been?

Atheism

2123 "Many . . . of our contemporaries either do not at all perceive, or explicitly reject, this intimate and vital bond of man to God. Atheism must therefore be regarded as one of the most serious problems of our time."

2124 The name "atheism" covers many very different phenomena. One common form is the practical materialism which restricts its needs and aspirations to space and time. Atheistic humanism falsely considers man to be "an end to himself, and the sole maker, with supreme control, of his own history."59 Another form of contemporary atheism looks for the liberation of man through economic and social liberation. "It holds that religion, of its very nature, thwarts such emancipation by raising man's hopes in a future life, thus both deceiving him and discouraging him from working for a better form of life on earth."60

2125 Since it rejects or denies the existence of God, atheism is a sin against the virtue of religion.61 The imputability of this offense can be significantly diminished in virtue of the intentions and the circumstances. "Believers can have more than a little to do with the rise of atheism. To the extent that they are careless about their instruction in the faith, or present its teaching falsely, or even fail in their religious, moral, or social life, they must be said to conceal rather than to reveal the true nature of God and of religion."

2128 Agnosticism can sometimes include a certain search for God, but it can equally express indifferentism, a flight from the ultimate question of existence, and a sluggish moral conscience. Agnosticism is all too often equivalent to practical atheism.

2134 The first commandment summons man to believe in God, to hope in him, and to love him above all else.

2140 Since it rejects or denies the existence of God, atheism is a sin against the first commandment.

The First Commandment

2089 "Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and catholic faith, or it is likewise an obstinate doubt concerning the same; apostasy is the total repudiation of the Christian faith; schism is the refusal of submission to the Roman Pontiff or of communion with the members of the Church subject to him."

Hell

1033 We cannot be united with God unless we freely choose to love him. But we cannot love God if we sin gravely against him, against our neighbor or against ourselves: "He who does not love remains in death. Anyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him."612 Our Lord warns us that we shall be separated from him if we fail to meet the serious needs of the poor and the little ones who are his brethren.613 To die in mortal sin without repenting and accepting God's merciful love means remaining separated from him for ever by our own free choice. This state of definitive self-exclusion from communion with God and the blessed is called "hell."

1034 Jesus often speaks of "Gehenna" of "the unquenchable fire" reserved for those who to the end of their lives refuse to believe and be converted, where both soul and body can be lost.614 Jesus solemnly proclaims that he "will send his angels, and they will gather . . . all evil doers, and throw them into the furnace of fire,"615 and that he will pronounce the condemnation: "Depart from me, you cursed, into the eternal fire!"616

1035 The teaching of the Church affirms the existence of hell and its eternity. Immediately after death the souls of those who die in a state of mortal sin descend into hell, where they suffer the punishments of hell, "eternal fire."617 The chief punishment of hell is eternal separation from God, in whom alone man can possess the life and happiness for which he was created and for which he longs.

1036 The affirmations of Sacred Scripture and the teachings of the Church on the subject of hell are a call to the responsibility incumbent upon man to make use of his freedom in view of his eternal destiny. They are at the same time an urgent call to conversion: "Enter by the narrow gate; for the gate is wide and the way is easy, that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard, that leads to life, and those who find it are few."

We have our moral laws that we believe we should follow. But no where in church teaching will it say we shouldn't be kind and respectful to those who don't (and as I've shown you, it says the opposite), nor should we claim to know or judge the state of soul of another person. So again, showing tolerance and affection to non Catholics is not contrary to my faith. There is no ulterior motive. We are taught to treat others with respect because every person has inherent human dignity.
