Baptism is a Christian sacrament of initiation almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or by immersing in water either partially or completely, traditionally three times, once for each person of the Trinity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. In certain Christian denominations, such as the Catholic Churches, Eastern Orthodox Churches, Oriental Orthodox Churches, Assyrian Church of the East, and Lutheran Churches, baptism is the door to church membership, with candidates taking baptismal vows. It has also given its name to the Baptist churches and denominations.
Religious conversion is the adoption of a set of beliefs identified with one particular religious denomination to the exclusion of others. Thus "religious conversion" would describe the abandoning of adherence to one denomination and affiliating with another. This might be from one to another denomination within the same religion, for example, from Protestant Christianity to Roman Catholicism or from Shi'a Islam to Sunni Islam. In some cases, religious conversion "marks a transformation of religious identity and is symbolized by special rituals".
Religion and mythology differ in scope but have overlapping aspects. Both are systems of concepts that are of high importance to a certain community, making statements concerning the supernatural or sacred. Generally, mythology is considered one component or aspect of religion. Religion is the broader term: besides mythological aspects, it includes aspects of ritual, morality, theology, and mystical experience. A given mythology is almost always associated with a certain religion such as Greek mythology with Ancient Greek religion. Disconnected from its religious system, a myth may lose its immediate relevance to the community and evolve—away from sacred importance—into a legend or folktale.
Secular humanism is a philosophy, belief system, or life stance that embraces human reason, logic, secular ethics, and philosophical naturalism, while specifically rejecting religious dogma, supernaturalism, and superstition as the basis of morality and decision-making.
Shunning can be the act of social rejection, or emotional distance.

Penance is any act or a set of actions done out of repentance for sins committed, as well as an alternate name for the Catholic, Lutheran, Eastern Orthodox, and Oriental Orthodox sacrament of Reconciliation or Confession. It also plays a part in confession among Anglicans and Methodists, in which it is a rite, as well as among other Protestants.
Psychology of religion consists of the application of psychological methods and interpretive frameworks to the diverse contents of religious traditions as well as to both religious and irreligious individuals. The various methods and frameworks can be summarized according to the classic distinction between the natural-scientific and human-scientific approaches. The first cluster amounts to objective, quantitative, and preferably experimental procedures for testing hypotheses about causal connections among the objects of one's study. In contrast, the human-scientific approach accesses the human world of experience using qualitative, phenomenological, and interpretive methods. This approach aims to discern meaningful, rather than causal, connections among the phenomena one seeks to understand.
In the study of religion, orthopraxy is correct conduct, both ethical and liturgical, as opposed to faith or grace. Orthopraxy is in contrast with orthodoxy, which emphasizes correct belief. The word is a neoclassical compound—ὀρθοπραξία meaning 'right practice'.
Spiritual ecology is an emerging field in religion, conservation, and academia that proposes that there is a spiritual facet to all issues related to conservation, environmentalism, and earth stewardship. Proponents of spiritual ecology assert a need for contemporary nature conservation work to include spiritual elements and for contemporary religion and spirituality to include awareness of and engagement in ecological issues.

In religion and philosophy, ensoulment is the moment at which a human or other being gains a soul.

In Christianity, self-flagellation is practiced in the context of the doctrine of the mortification of the flesh and is seen as a spiritual discipline.

Body piercing, which is a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewellery may be worn, or where an implant could be inserted. The word piercing can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. It can also, by metonymy, refer to the resulting decoration, or to the decorative jewelry used. Piercing implants alter the body and/or skin profile and appearance. Although the history of body piercing is obscured by popular misinformation and by a lack of scholarly reference, ample evidence exists to document that it has been practiced in various forms by both sexes since ancient times throughout the world. Body piercing can be performed on people of all ages, although most minors are only permitted to have earlobe piercings.
