Written sources mention a church at Reftele as early as 1311, and it is thought that both church and churchyard were established here in the medieval period. By the 18th century the old building and its churchyard had become too cramped, but the site's position on a plateau made expansion difficult, eventually prompting a completely new church.
Construction of the present building began in 1835 under master builder Johan Wennberg, to designs by architect Per Axel Nyström. It was consecrated in 1839 by Bishop Esaias Tegnér, with the sale of the old church's lead roofing helping to fund the new construction. The church has a rectangular nave with a rounded chancel to the east, a west tower containing the main entrance, and a north sacristy. The roofs, originally covered with wooden shingles, are now clad in copper, and the church is whitewashed inside and out.
A thorough renovation took place in 1931–32 under architect Paul Boberg, during which artist Waldemar Lorentzon, a member of the Halmstad Group, painted the chancel ceiling with a depiction of Christ's commission to the apostles, showing the figure of Christ surrounded by the twelve disciples. Further, more extensive changes followed in the late 1960s, when architect Ingeborg Waern-Bugge oversaw both exterior and interior modernisation, including new flooring, altered gallery seating to accommodate a choir, and a bold contemporary colour scheme typical of the period.
Among the church's furnishings is a sandstone font believed to date from the 12th century, carved in three sections with motifs including trees, lions, human heads, saints and a depiction of Christ in Majesty — making it considerably older than the current building. The altarpiece, painted in 1904 by Gottfrid Kallstenius, depicts Christ's meeting with Mary outside the tomb; an earlier altar painting from 1871 survives hidden behind it. A bridal crown dating from the 1600s was originally shared jointly with the neighbouring Anderstorp parish before being bought outright by Reftele in the 19th century.
A stone chapel with a slate roof was built in the churchyard in 1963, designed to harmonise with the church's copper roofing and the churchyard walls. The church has had several organs over the years, the earliest recorded from 1844, with the current main organ dating from 1965 and incorporating the older instrument's façade.
