As the rubrics stand, such persons, unless and until actually confirmed, have no right to require a clergyman to admit them to Communion, and he commits no legal offence by refusing to do so. On the other hand, a considerable number of such persons do, as a matter of fact, communicate in our Church without having been confirmed or being desirous to be confirmed; and a clergyman who admits them, in the absence of any direction of the bishop to the contrary,[209] may be acting in a wise and Christian manner. 8. The rubrics of the Communion Office prescribe that a sermon or one of the authorised homilies shall follow the Nicene Creed whenever that portion of the office is used, whether a Communion actually takes place afterwards or not. And the 45th Canon enjoins the preaching of one sermon every Sunday of the year. The power of the bishop to require a second and even, in certain cases, a third sermon has already been noticed.[210] But, inasmuch as the Prayer Book contains no direction that sermons shall follow Matins or Evensong, such sermons may be regarded as in the nature of separate or additional services. The 55th Canon prescribes that all sermons, lectures, and homilies shall be preceded by what is called the Bidding Prayer and the Lord's Prayer. But this rule is not in practice observed in the case of sermons in the middle of the Communion Service or immediately following some other service. Under the Act of Uniformity Amendment Act of 1872, Morning and Evening Prayer, the Litany, and Holy Communion may any of them be used with or without the preaching of a sermon or lecture or the reading of a homily; and a sermon or lecture may be preceded either by one of the services appointed by the Prayer Book or by a service authorised by that Act, or by a Collect taken from the Prayer Book, with or without the Lord's Prayer.[211] 9. Regular catechising is enjoined both by the Canons and by the Prayer Book. But the direction in the 59th Canon, that it shall take place for half-an-hour or more before Evening Prayer, is superseded by the rubric at the end of the Catechism, which requires the incumbent of every parish diligently upon Sundays and holy days, after the second lesson at Evening Prayer, openly in the church to instruct and examine so many children of his parish sent to him as he shall think convenient, in some part of the Catechism.
