Abjura'tion. n.s. [from abjure.] The act of abjuring. The oath taken for that end.
Until Henry VIII. his time, if a man, having committed felony, could go into a church or church-yard, before he was apprehended, he might not be taken from thence to the usual trial of law, but confessing his fault to the justices, or to the coroner, gave his oath to forsake the realm for ever, which was called abjuration.
There are some abjurations still in force among us here in England; as, by the statute of the 25th of king Charles II. all persons that are admitted into any office, civil or military, must take the test; which is an abjuration of some doctrines of the church of Rome.
There is likewise another oath of abjuration, which laymen and clergymen are both obliged to take; and that is, to abjure the Pretender. Ayliffe's Parergon Juris Canonici.
