The regulative principle regarding worship, which distinguishes the Calvinist approach to the public worship of God from other views, is that only those elements that are instituted or appointed by command or example in the New Testament are permissible in worship. In other words, the regulative principle maintains that God institutes in the scriptures what he requires for worship in the church, and everything else is prohibited. As the regulative principle is reflected in Calvin's own thought, it is driven by his evident antipathy toward the Roman Catholic Church and her worship, and it associates musical instruments with icons, which he considered violations of the Ten Commandments' prohibition of graven images.

I was under the impression that the "five points" and even the TULIP acrostic was developed by Calvinists... stemming from the "Canons of Dort" and what all.  I could be wrong... Googling it now.

That's what I thought.

The TULIP is a cute little acronym that they invented in the Netherlands to show the error of the Remonstrants (the five points of Arminianism). After a council was held in Dort (can't spell the whole word), freewill theology was labeled heresy and the Church resumed with what you guys call Calvinism.

The Synod of Emden was a gathering of 29 exiled Calvinist Church leaders (Ministers and Authors) who were to become the founders of the Dutch Reformed Church. Held in Emden, Germany on 4 October 1571, where it established the rules and doctrices of the Dutch Reformed Church.

Article 1.
[Conditional Election - corresponds to the second of TULIP’s five points, Unconditional Election]
That God, by an eternal and unchangeable purpose in Jesus Christ his Son before the foundation of the world, has determined that out of the fallen, sinful race of men, to save in Christ, for Christ’s sake, and through Christ, those who through the grace of the Holy Spirit shall believe on this his son Jesus, and shall persevere in this faith and obedience of faith, through this grace, even to the end; and, on the other hand, to leave the incorrigible and unbelieving in sin and under wrath and to condemn them as alienated from Christ, according to the word of the Gospel in John 3:36: “He that believes on the Son has everlasting life: and he that does not believe the Son shall not see life; but the wrath of God abides on him,” and according to other passages of Scripture also.

Article 2.
[Unlimited Atonement - corresponds to the third of TULIP’s five points, Limited Atonement]
That, accordingly, Jesus Christ the Savior of the world, died for all men and for every man, so that he has obtained for them all, by his death on the cross, redemption and the forgiveness of sins; yet that no one actually enjoys this forgiveness of sins except the believer, according to the word of the Gospel of John 3:16, “For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.”  And in the First Epistle of John 2:2: “And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.”

Article 3.
[Deprivation - corresponds to the first of TULIP’s five points, Total Depravity]
That man does not posses saving grace of himself, nor of the energy of his free will, inasmuch as in his state of apostasy and sin he can of and by himself neither think, will, nor do any thing that is truly good (such as saving Faith eminently is); but that it is necessary that he be born again of God in Christ, through his Holy Spirit, and renewed in understanding, inclination, and will, and all his faculties, in order that he may rightly understand, think, will, and effect what is truly good, according to the Word of Christ, John 15:5, “Without me you can do nothing.”

Article 4.
[Resistible Grace - corresponds to the fourth of TULIP’s five points, Irresistible Grace]
That this grace of God is the beginning, continuance, and accomplishment of all good, even to the extent that the regenerate man himself, without prevenient or assisting, awakening, following and cooperative grace, can neither think, will, nor do good, nor withstand any temptations to evil; so that all good deeds or movements that can be conceived must be ascribed to the grace of God in Christ. But with respect to the mode of the operation of this grace, it is not irresistible, since it is written concerning many, that they have resisted the Holy Spirit (Acts 7, and elsewhere in many places).

Article 5.
[Assurance and Security - corresponds to the fifth of TULIP’s five points, Perseverance of the Saints]
That those who are incorporated into Christ by true faith, and have thereby become partakers of his life-giving Spirit, as a result have full power to strive against Satan, sin, the world, and their own flesh, and to win the victory; it being well understood that it is ever through the assisting grace of the Holy Spirit; and that Jesus Christ assists them through his Spirit in all temptations, extends to them his hand, and if only they are ready for the conflict, desire his help, and are not inactive, keeps them from falling, so that they, by no deceit or power of Satan, can be misled nor plucked out of Christ’s hands, according to the Word of Christ, John 10:28: “Neither shall any man pluck them out of my hand.” But whether they are capable, through negligence, of forsaking again the first beginning of their life in Christ, of again returning to this present evil world, of turning away from the holy doctrine which was delivered them, of losing a good conscience, of neglecting grace, that must be more particularly determined out of the Holy Scripture, before we ourselves can teach it with the full confidence of our mind.

These Articles, thus set forth and taught, the Remonstrants deem agreeable to the Word of God, tending to edification, and, as regards this argument, sufficient for salvation, so that it is not necessary or edifying to rise higher or to descend deeper.

One also needs to realize TULIP is a characterization of beliefs by those that don't share them.  TULIP was derogatory.
