How then did the Samaritans know not what they worshiped? Because they thought that God was local and partial; so at least they served Him, and so they sent to the Persians, and reported that the God of this place is angry with us 2 Kings 26, in this respect forming no higher opinion of Him than of their idols. Wherefore they continued to serve both Him and devils, joining things which ought not to be joined. The Jєωs, on the contrary, were free from this supposition, at least the greater part of them, and knew that He was God of the world. Therefore He says, You worship ye know not what; we know what we worship.

Do not wonder that He numbers Himself among Jєωs, for He speaks to the woman's opinion of Him as though He were a Jєωιѕн Prophet, and therefore He puts, we worship. For that He is of the objects of worship is clear to every one, because to worship belongs to the creature, but to be worshiped to the Lord of the creature. But for a time He speaks as a Jєω; and the expression we in this place means we Jєωs. Having then exalted what was Jєωιѕн, He next makes Himself credible, and persuades the woman to give the greater heed to His words, by rendering His discourse above suspicion, and showing that He does not exalt what belongs to them by reason of relationship to those of His own tribe.

For it is clear, that one who had made these declarations concerning the place on which the Jєωs most prided themselves, and thought that they were superior to all, and who had taken away their high claims, would not after this speak to get favor of any, but with truth and prophetic power. When therefore He had for a while removed her from such reasonings, saying, Woman, believe Me, and what follows, then He adds, for salvation is of the Jєωs. What He says is of this kind: neither, that blessings to the world came from them, (for to know God and condemn idols had its beginning from them, and with you the very act of worship, although ye do it not rightly, yet received its origin from them,) or else, He speaks of His own Coming. Or rather, one would not be wrong in calling both these things salvation which He said was of the Jєωs; which Paul implied when he said, Of whom is Christ according to the flesh, who is God over all. Romans 9:5 Do you see how He commends the old Covenant, and shows that it is the root of blessings, and that He is throughout not opposed to the Law, since He makes the groundwork of all good things to come from the Jєωs?

I think you can still find it, say when a married couple converts, and say a teenage child goes along to Mass on Sunday but doesn’t really believe or care. Or someone “converts” because their sweetie pie wants to get married in a Church.

I, N.N., .... years of age, born outside the Catholic Church, have held and believed errors contrary to her teaching. Now, enlightened by divine grace, I kneel before you, Reverend Father ...., having before my eyes and touching with my hand the holy Gospels. And with firm faith I believe and profess each and all the articles contained in the Apostles' Creed, that is: I believe in God, the Father almighty, Creator of heaven and earth; and in Jesus Christ, His only Son, our Lord, who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died, and was buried; He descended into hell, the third day He arose again from the dead; He ascended into heaven, and sits at the right hand of God, the Father almighty, from there He shall come to judge the living and the dead. I believe in the Holy Spirit; the holy Catholic Church; the communion of saints; the forgiveness of sins; the resurrection of the body, and life everlasting. Amen.

I firmly admit and embrace the apostolic and ecclesiastical traditions and all the other constitutions and ordinances of the Church.

I admit the Sacred Scriptures in the sense which has been held and is still held by holy Mother Church, whose duty it is to judge the true sense and interpretation of Sacred Scripture, and I shall never accept or interpret them in a sense contrary to the unanimous consent of the fathers.

I profess that the sacraments of the New Law are truly and precisely seven in number, instituted for the salvation of mankind, though all are not necessary for each individual: baptism, confirmation, holy Eucharist, penance, anointing of the sick, holy orders, and matrimony. I profess that all confer grace, and that baptism, confirmation, and holy orders cannot be repeated without sacrilege. I also accept and admit the ritual of the Catholic Church in the solemn administration of all the aforementioned sacraments.
I accept and hold in each and every part all that has been defined and declared by the Sacred Council of Trent concerning original sin and justification. I profess that in the Mass there is offered to God a true, real, and propitiatory sacrifice for the living and the dead; that in the holy sacrament of the Eucharist the body and blood together with the soul and divinity of our Lord Jesus Christ is really, truly, and substantially present, and that there takes place in the Mass what the Church calls transubstantiation, which is the change of all the substance of bread into the body of Christ and of all substance of wine into His blood. I confess also that in receiving under either of these species one receives Jesus Christ whole and entire.

I firmly hold that Purgatory exists and that the souls detained there can be helped by the prayers of the faithful.

Likewise I hold that the saints, who reign with Jesus Christ, should be venerated and invoked, that they offer prayers to God for us, and that their relics are to be venerated.
I firmly profess that the images of Jesus Christ and of the Mother of God, ever a Virgin, as well as of all the saints should be given due honor and veneration. I also affirm that Jesus Christ left to the Church the faculty to grant indulgences, and that their use is most salutary to the Christian people. I recognize the holy, Roman, Catholic, and apostolic Church as the mother and teacher of all the churches, and I promise and swear true obedience to the Roman Pontiff, successor of St. Peter, the prince of the apostles and vicar of Jesus Christ.

Moreover, without hesitation I accept and profess all that has been handed down, defined, and declared by the sacred canons and by the general councils, especially by the Sacred Council of Trent and by the Vatican General Council, and in special manner all that concerns the primacy and infallibility of the Roman Pontiff. At the same time I condemn and reprove all that the Church has condemned and reproved. This same Catholic faith, outside of which none can be saved, I now freely profess and I truly adhere to it. With the help of God, I promise and swear to maintain and profess this faith entirely, inviolately, and with firm constancy until the last breath of life. And I shall strive, as far as possible, that this same faith shall be held, taught, and publicly professed by all who depend on me and over whom I shall have charge.
So help me God and these holy Gospels.

Although it is impossible to be "re-baptised", Jayne, it is not too late to make that Confession of the Faith, before a priest or privately, before God. It has only to be written on your heart, no?

Cantarella made the following quote & cited Pope Gregory XIII's Bull regarding the problem of false conversions of Jєωs as a means to infiltrate the Church, and it's very relevant to this topic:

"It is historical fact that the Jєωs have been behind the worse revolutions against the Church of Christ. (Reformation..."

"As we see, the Jєωιѕн infiltration have always been a thread for the Church but never seemed so victorious and evident as with Vatican II Council"

The Reformation? Martin Luther on the Jєωs: “Set fire to their ѕуηαgσgυєs or schools. Jєωιѕн houses should “be razed and destroyed,” and Jєωιѕн “prayer books and тαℓмυdic writings, in which such idolatry, lies, cursing, and blasphemy are taught, [should] be taken from them.” In addition, “their rabbis [should] be forbidden to teach on pain of loss of life and limb.” Still, this wasn’t enough.
Luther also urged that “safe-conduct on the highways be abolished completely for the Jєωs,” and that “all cash and treasure of silver and gold be taken from them.”
