Initiation of those who have not yet been baptized into the Church happens most prominently at the Easter Vigil. On that night, catechumens complete their preparation and are baptized, then confirmed, and receive the Eucharist for the first time, formally joining the Catholic Church. The Easter Vigil symbolizes new life in Christ, making it the traditional moment for welcoming catechumens into full communion. Pentecost marks the coming of the Holy Spirit and the growth of the Church, but it is not the standard time for catechumen reception. The Feast of Booths is a Jewish festival and has no place in Christian initiation. Christmas Eve is a major vigil before Christmas but is not the typical day for the catechumen reception ceremony.

Sutra is a concise teaching text or discourse that serves as a short, memorable thread of instruction. In Buddhism, sutras are the Buddha’s sermons and dialogues recorded as scripture. In Hinduism, sutras appear as compact manuals or aphorisms that summarize larger systems—think of the Yoga Sutras or the Brahma Sutras. In Jainism, sutras appear in the Agama literature, presenting compact doctrinal guidance. The word itself evokes something tight and to the point, meant to be transmitted and recalled easily. That’s why describing a sutra as a short scriptural text or discourse used in Hinduism, Buddhism, and Jainism fits best. The other options describe things that aren’t sutras: long legal codes, prayers, or festivals associated with other traditions.

Baptism in the early church was the rite that brought someone into the Christian community, typically after a period of instruction or a profession of faith. By the third century, baptizing infants had become common in many communities, as evidenced by references to household baptisms and the practice of including children in the rite. This is why the statement about infant baptism being normal in the third century is the best fit: it reflects how baptism expanded beyond one-off adult conversions to include infants within the faith community. The method of baptism wasn't limited to immersion; while immersion was common for many adult converts, pouring (affusion) and sprinkling were also practiced, especially for infants or those who couldn’t be immersed. Baptism was not reserved only for those who asked after instruction; rather, communities typically baptized after some catechetical preparation, though eager converts and households seeking entry were often baptized as well. And though Easter was a significant and traditional time for baptisms, the rite occurred at other times too, depending on local practice.

The main idea here is that the Guru Granth Sahib is the living guide for Sikhs. It’s not just a book; after the ten human Gurus, Sikhs regard this scripture as the eternal Guru, the source of spiritual authority that shapes worship and daily life. In gurdwaras it rests on a throne, is read aloud in services, and its hymns—composed by the Sikh Gurus and other saints—inform prayers, philosophy, and how believers treat others. Because it’s considered a living Guru, its authority extends to doctrine, ethics, and community conduct, guiding practices like remembering God, working honestly, serving others, and practicing equality. This makes it central to both personal devotion and communal worship, far beyond a ceremonial text or a simple collection of hymns.

Secularism keeps government and public policy separate from religious influence, aiming for neutrality in public institutions. Religious fundamentalism, on the other hand, pushes for strict, literal religious interpretations to shape public life, laws, and social norms. So secularism reduces religious control over governance, while fundamentalism seeks to bring a specific religious framework into public life. The other statements mix up these roles or describe beliefs rather than governance aims, making the separation-and-neutrality contrast the best fit.
