I wonder when it's most appropriate to bow when making the sign of the cross. I bow at "God save me a sinner (x3)" during my prayers, and when anything is chanted three times at liturgy.
When else should we bow? Since converting, I've gone from not bowing at all, moderately bowing, and now I'm a bowing fiend. When exactly is it not appropriate to bow after making the sign of the cross?
You do it just about all the time during Great Lent! (as bows become prostrations, and crossing becomes a bow). Otherwise, the times you've mentioned above are dead on. You can bow at the refains of a canon (sentences chanted at Matins like, "O Holy Martyr Name
, pray to God for us!" or "Glory O Lord to thy Holy Resurrection!", and then cross yourself at "Glory..." and "Both now...", which are the standard refrains at the end of an ode (this is also transformed at Lent, particularly for the Great Canon of St. Andrew of Crete, when we prostrate at "Have mercy on me, O God..." and bow at the "Glory..." and "Both now..."
At the Liturgy, you can also bow in the anaphora at "It is meet and right...", "Take eat...", "drink of it all of you..." and "Thine Own of Thine Own..." Also, during the actual epiclesis at "make this bread...", "make what is in this cup..." and "changing them by the Holy Spirit. Amen! Amen! Amen!" bowing at the final "Amen." If it is not a Sunday, you make a full prostration at the end of the Amens (and some traditions will prostrate here even on a Sunday. It's quite beautiful.) You also bow immediately after the priest proclaims "Especially for Our Most Holy, Most Pure, Most Blessed and Glorious Lady Theotokos and Ever-Virgin Mary!"
You may also bow as the priest stands on the solea with the Gifts and proclaims "In the fear of God..." (this is a prostration if not on a Sunday or Feast of the Lord). And finally, you may bow at the end of the Liturgy at "...now and ever and unto ages of ages!" When the priest moves the remaining Gifts from the Altar back to the Table of Oblation (if you have communed. If not, it's a prostration....unless its Sunday or a Feast of the Lord, then bow regardless).
If I've forgotten anything, my apologies! I'm definitely open to additions to and corrections of what I've said, and I hope I've been helpful!
